Question

(a-b)^3 x (a+b)^2

A+B ka cube multiplied by A+B ka square.

Answer 1

Answer:That is,  

(a + b)3  =  (a + b)(a + b)(a + b)

Multiply (a + b) and (a + b).

(a + b)3  =  (a2 + ab + ab + b2)(a + b)

Simplify.

(a + b)3  =  (a2 + 2ab + b2)(a + b)

(a + b)3  =  a3 + a2b + 2a2b + 2ab2 + ab2 + b3

Combine the like terms.  

(a + b)3  =  a3 + 3a2b + 3ab2 + b3

or

(a + b)3  =  a3 + b3 + 3ab(a + b)
