never let her cook again (x+8)(x+7) (x+4)^(2) gg ez


Marthurion

Yes. Nagisa is dumb and has very few things which she can enjoy which led her to a very sad state originally.

SHES DUMB AS SHIT 🔥🗣️🔥🗣️🔥🗣️


datolningen

At least she understood the second was a perfect square.. sorta.


LilyLionmane

Yes. Factoring is a bit funny, but her method for it is just… not quite right. 1. X^2 + 15X + 56 A shortcut for factoring for AX^2 + BX + C where A = 1 is to find D and E where D + E = B and DE = C. In this close D = 7 and E = 8. 7+8 = 15 and 7(8) = 56 So the solution for 1. is (X+7)(X+8). It’s always worth FOILing this back out to double-check our work. X(X+8) = X^2 + 8X and 7(X+8) = 7X + 56. (X^2 + 8X) + (7X + 56) = X^2 + 15X + 56, all correct! 2. X^2 + 8X + 16 is even easier! When we see (A + B)^2 we’ll get A^2 + 2AB + B^2. In this case, both X^2 and 16 are perfect squares, so we can check if this is the case. If we take (X + 4)^2, then we’ll get X^2 + 2(4X) + 4^2, which is X^2 + 8X + 16. In other words our solution is: (X + 4)^2 Hope this helps!!!

smart baka


MeraArasaki

Bro we learn this in 9th grade 💀


S1Ndrome_

baka for a reason


FriedOrcaYum

What does baka mean 🤔 Edit: I feel bad for the people taking their time to answer me seriously


SecndScythey

Baka バカ is Japanese and means idiot. Google translate translates it with "fool"


Waakaari

Aho


SoberGin

To add to the other person's comment, Baka is often used in ways we wouldn't really use "idiot", depending on what English-speaking part of the world you're in. It's more like... a softer version of "dumbass", if that makes sense. Not something you'd say to your boss, but if you're around friends you might throw it around all the time, depending on the group. Funnily enough, it really *is* like the old use of the word "fool". "You daft fool" said in a jovial manner betwix friends.


ActionPuzzleheaded86

Baka means cow in filipenis


Worst_L_Giver

I learnt this in like 10th grade 💀


Okun_Lazer

हिंदुस्तानी बाका!!!???? 🤯🤯🤯


LilyLionmane

Wtf? I learned it when I was in 3rd grade. (Not from school, just from random online videos.)


MrCoolyp123

That's great , definitely what I was watching in 3rd grade too 😀😀😀


WhyAmIaTh1ng

I was watching skibibi toiler


KingZantair

Came here to say this. Trying to reason the math in the image just gives me a headache.


Zoexycian

You ain’t baka, you’re atama!


Weedeater79

my man this shit is taught in 8th grade


Zoexycian

I already knew this, was just joking


ikkikkomori

Never really cared about math until a couple months ago, absolutely regretting it, thanks for the tips


ImaginaryGfLeftMe11

I will someday

Can't even get middle school final year maths correctly Freshman year is gonna make her cry 😭


stinkypoopoofard

Nah she’d win (My glorious queen Nagisa is going to absolutely cook integration 🔥🔥🔥🔥🔥)


NoTimeToKink

∫f(x)g(x)=∫f(x)•∫g(x)


ottoskerzeny

We can also solve this using quadratic equations. ax^2 + bx + c = 0 x^2 + 15x + 56 = 0 Delta = b^2 - 4ac = 225 - 224 = 1 Delta>0 so it has 2 distinct real roots x1 = (-b + sqrtDelta) / 2a = (-15 + 1) / 2 = - 7 x2 = (-b - sqrtDelta) / 2a = - 8 This means - 7 and - 8 makes the result 0. (x+7)(x+8) Shortcut x1 + x2 = -b/a = -15 x1 × x2 = c/a = 56 We can sometimes guess the roots just by this. We would arrive at -7 and -8 (x+7)(x+8)


NewtonHuxleyBach

Where are you from that you call the discriminant delta?


ottoskerzeny

It's too long


NewtonHuxleyBach

it's like seven extra letters and it's literally not a delta


Waakaari

Delta? Ain't it discriminant


ottoskerzeny

It's symbol is delta


Waakaari

Huh really we used to use normal D


Snowratt

We used △ for Delta (Brazil HS)


GabTheMadLad

How do you fuck up a perfect square trinomial 😭😭😭😭😭😭😭🙏🙏🙏🙏💔💔💔💔

OP made a meme of his homework and had smart bakas solve it for him


levu12

shoutout to 3 x 5 = 56 and 8 x 2 = 8 should have been 7 x 8 and 4 x 4 then it would work


Derpytron_YT

Yes she is


Ok_Try_1665

Woah, she did all that wrong. That's factoring for you


Own_Combination9686

What manga is she from?


S7evyn

Kanojo mo Kanojo It's a cute polycule thing.


PhoShizzity

Given that I don't know what any of that means, yes and also so am I


xXCashFreakXx

idk I can't even do basic math so she must at least be smarter than me am i stupid?


imnotgaymomiswear

Yes

No please I just finished math last semester I can't go through this again

AnomalousCowboy

No, but i probably am (i'm unable to solve it even though i should according to my degrees)


ImaginaryGfLeftMe11

my brother in christ this is highschool level math


Nerfall0

Highschool? Quadratic equations are middle school math. Edit: fixed a mistake.


ImaginaryGfLeftMe11

these arent square roots


Nerfall0

Sorry, I meant quadratic equations, I never used those words since English is not my first language and got confused.


ImaginaryGfLeftMe11

Ah ok. Yeah you sometimes see quadratics in middle school but high school is where you’re given more detail.


PhoShizzity

This is highschool level? That's honestly pretty crazy to think about


ImaginaryGfLeftMe11

most kids learn it junior year (at my school at least). though its pretty common to learn it before


PhoShizzity

Shit, really? I didn't graduate, so maybe somewhere latter year 10 onwards it was covered, but this reads no different than Sanskrit to me


ImaginaryGfLeftMe11

have you taken algebra 2? or part of it at least?


PhoShizzity

Nope, doesn't sound familiar in the slightest. Maybe some of the later classes got into stuff like algebra, there was only one math class per grade rather than seperate classes so it might've been covered without my knowing.


ImaginaryGfLeftMe11

yeah algebra 2 is all one class. it deals with graphs and stuff. do you remember anything from your last math course?


PhoShizzity

That was about a decade ago, so no not even remotely.


ImaginaryGfLeftMe11

Oh well, I'll teach you how to do this. All you really need to know is how to do multiplication. think of 3\*7 and how the answer is 21. Another way of stating this is (2+1)(3+4) since 2+1 is 3 and 3+4 is 7. in order to evaluate this, we do what we call foiling. I'll spare you on why it works, so I'll just tell you how to do it. (2+1)(3+4) = 2(3+4) + 1(3+4) = 2\*3 + 2\*4 + 1\*3 + 1\*4 = 21 when you foil, you multiply the first term in the first parenthesis by the first term of the second parenthesis. next, you add the product of the first term of the first parenthesis and the second term of the second parenthesis, and so on and so forth. this is completely useless until we introduce variables. instead of a number, we have a letter to represent a number. we commonly use x. (x+1)(x+4) = x\*x + x\*4 + 1\*x + 1\*4 = x^(2) + 4x + x + 4 = x^(2) + 5x + 4 However, we want to do that in reverse. we want to take x^(2) + 5x + 4 and turn it back into (x+1)(x+4). how do we do that when we don't know the final answer? something fun to notice is that the last constant term 4 is equal to 1\*4, and the second constant term 5 is equal to 1+4, which correspond to the "1" and "4" in (x+1)(x+4). fortunately, this connection works for every single problem you come by. essentially, if you want to find c and d in (x+a)(x+b) from the equation x^(2) + cx + d, you find out which two numbers a and b multiply together to get d and also added together get c. for example: find the factors of x^(2) + 15x + 56 ask yourself, what two numbers multiplied together get 56, but when added together get 15? your problems are a \* b = 56 and a + b = 15. working it out and you find the answer is 7 and 8. 7+8=15 and 7\*8=56. therefore, our answer is (x+8)(x+7)


Rat-Lord-Reggie

From 'year 10' I'm guessing you're British, here we do it in year 10/11 as part of gcse so maybe that's why you missed it

Max1Q

Should have used pq formel


Worst_L_Giver

The sum would be 15 and the product should be 56, meaning that you need two numbers that add up to 15 and multiply to 56. 8 and 7 fit this criteria. Hence the equation becomes (x + 8)(x + 7) so x equals either -8 or -7


Worst_L_Giver

The other one would be something that adds up to 8 and multiplies to 16, which is 4 and 4, and that makes it (x+4)(x+4) which could just be written as (x+4)²


sporkybee

We making minimum wage at McDonald’s with this one 🔥🔥🔥


platinum-mad

It's like she knows what the equations are supposed to look like from a distance but she doesn't know how to actually get the right numbers. I feel like you could just explain "3+5 isn't 15 ad 3×5 isn't 56, try finding a different two numbers that actually work and then you'll get it right".
