what is the technique in solving sum and difference of two cubes

Sagot :

Steps:
1. Find the cube root of first and second term
2. In the Binomial obtained,square the first and second terms. to get the middle term, get the negative of product af first and second term

Ex. y cubed - 27 = (y-3)(y squared + 3y +9)
