A doubt of factorization

OpenStudy (osanseviero):

\[11x ^{3}\left( x ^{3}-2y ^{2} \right)^{4} \times \left( 11y ^{5}\left( x ^{3}-2y ^{2} \right)^{2}+6x \left( x ^{3}-2y ^{2} \right)-12x ^{2}y \right)\]

OpenStudy (osanseviero):

I already did the first part, but now i am here...what should I do now?

OpenStudy (osanseviero):

dont answer it, just tell me which should be my next step

OpenStudy (shubhamsrg):

let x^3 - 2y^2 = t , say then simplify in the end you may substitute back t that should make it bit easier.

OpenStudy (osanseviero):

\[11x ^{3}t ^{4}\times \left( 11y ^{5}t ^{2}+6xt-12x ^{2y} \right)\]

OpenStudy (osanseviero):

the last y is not an exponent...so now what should I do? I think I need 2 numbers that multiplied are -132 and added are 6..is that correct?

OpenStudy (shubhamsrg):

yep..thats what even i'd think..

OpenStudy (shubhamsrg):

did you get anyhting? coz i couldnt,,hmmn..

OpenStudy (osanseviero):

nope hehe...then i guess that this is the end of the problem
