x^3 + 64
x^3 + 4^3
there is a identity a^3 + b^3 =( a+b)(a^2- ab +b^2)
so come on to your question.
x^3 + 4^3
(x+4){(x)^2 - 4x + 4^2}
(x+4)(x^2- 4x +16)
your answer is (x+4)(x^2-4x+16)
x^3 + 4^3
there is a identity a^3 + b^3 =( a+b)(a^2- ab +b^2)
so come on to your question.
x^3 + 4^3
(x+4){(x)^2 - 4x + 4^2}
(x+4)(x^2- 4x +16)
your answer is (x+4)(x^2-4x+16)
hope it helps
