Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Which expression is the completely factored form of x3 + 8y6 ?

Answer 1

`x^3+8y^6=x^3+2^3(y^2)^3=x^3+(2y^2)^3\\\\\text{use}\ a^3+b^3=(a+b)(a^2-ab+b^2)\\\\x^3+(2y^2)^3=(x+2y^2)(x^2-(x)(2y^2)+(2y^2)^2)=(x+2y^2)(x^2-2xy^2+4y^4)`

`Answer:\ (x+2y^2)(x^2-2xy^2+4y^4)`
