It’s just a perfect square trinomial and a difference of squares

Thanks

#

Can u do this

#

I can do c just do d

Heyy

#

Wait which one

#

For d

#

=(x-5a)^2-(y+1)^2

#

=(x-5a+y+1)(x-5a-y-1)

#

Nvm i can do d no too

#

for c use substitution, let t = x²

#

it becomes 4t² + 16t+ 9

#

idk if we can split middle term here but u can something better here
add 7 and subtract 7

#

It becomes : 4t² + 16t + 4² - root 7 squared

#

(4t+4)² - root 7 squared

#

final answer : (4x²+4+ root 7)(4x²+4- root 7)

#

maybe u can factorize these quadratics too but i'll leave that to ya

God damn

lol this isn't "simple"

#

You know the thing I hate about factoring is that if you’re given just a random polynomial the chance it factors neatly is so small

#

All the techniques we learn only work with very specific cases

#

The question has to be designed to factor nicely

dark compass **Daniel\_The\_Maniel**

WAit this is wrong

#

It should be $(xy+x-y+1)(xy-x+y+1)$
