Question

what is the factor of 64x3-8 then solve it?

Answer 1

(64x^3) -8 = 4^3*x^3-2^3 = (4x)^3 - 2^3
I think you have a formula for the rest?

Answer 2

hint: a^3-b^3=(a-b)(a^2+ab+b^2)

Answer 3

can you solve the given factor?

Answer 4

I have showed you how
you have (4x)^3-2^3
and a^3-b^3 = (a-b)(a^2+ab+b^2)
so let a = 4x and b= 2
what do you have?

Answer 5

can you give me on how to check my answer if its right?
