Answer 1

Answer: a³-b³= (a-b)(a²+ab+ b²)

Expressed in words, the difference of the cubes of two quantities is the product of the difference of the two quantities by the “imperfect square of the su

Answer 2

Answer:

a3+3a2b+3a2b+b3

Explanation:

(a + b)3 = (a + b)(a + b)(a + b)

= (a2 + 2ab + b2)(a + b)

= a3 + a2b + 2a2b + 2ab2 + ab2 + b3

= a3 + 3a2b + 3ab2 + b3

= a3 + 3ab(a+b) + b3

Therefore, (a + b)^3 formula is:

(a + b)3 = a3 + 3a2b + 3ab2 + b3
