Factoring Polynomials
(please show step by step)
8z^3 + 512w^3

I see cubes all over the place, you should be familiar with the factors of A^3 + Bb^3 = (A+B)(A^2  AB + B^2) and its equivalent of A^3  B^3
8z^3 + 512w^3
= (8z^3  512w^3)
=  (5z  8w)(25z^2 + 40wz + 64w^2)

In which step is the error? Step 1: Let x = 1 and y = 1. Step 2: By substitution xy = y^2. Step 3: Multiplying both sides by 1, xy= y^2. Step 4: Adding x^2 to both sides, x^2xy=x^2y^2. Step 5: Factoring, x(xy)=(x+y)(xy). Step
