ok bro

like

really

are u even trying

or just trolling

legot

x^2 - y^2 = (x-y) (x+y)

substitute values

8*4 = 32

here's ur dumb answer

[unique ice]

dumb

[midnight wind]

it was exceptionally simple if u know the identity

[unique ice]

x+y=-4
x-y=8
find y^2-x^2

[unique ice]

3rd identity doesnt apply

[midnight wind]

wtf is this

[unique ice]

its not x^2-y^2 it is y^2-x^2

dumbo

[midnight wind]

alr

[unique ice]

plus its -32 if u do dat cuz its -4

u r dumb ++

[midnight wind]

u could just

solve for x and y

and then

just squrw

[unique ice]

what

[midnight wind]

its a linear eqn in 2 variables just find x and y

like y = -6 and x = 2

after solving with like elimination or subs method

or any

then just

[unique ice]

ikr

but its in algebric identities chapter

[midnight wind]

bro literally what do they want us to do fr

[unique ice]

and our teacher said all the questions should be solved with algebric identities or you wont get marks

[unique ice]

fr

[midnight wind]

ok lemme try

nah we're dumb

we can multiply y-x = 8 vy -1

by*

gives us -y + x = -8

and put it in (y-x)(x+y)

so like

-8*-4 = 32

@unique ice

[unique ice]

oh

ty

[midnight wind]

what are we doing bro
