Question

How to multiply algebraic expression.

Answer 1

We take the 2 terms of the first bracket and multiply both of them by the second bracket.

(2x + 3)(x2− x − 5)

= (2x)(x2 − x − 5) + (3)(x2 − x − 5)

= (2x3 − 2x2 − 10x) + (3x2 − 3x − 15)

= 2x3 + x2 − 13x − 15

This time we could collect together some like terms. There was:

−2x2 + 3x2 = x2

and

−10x − 3x = −13x

follow me please please please making efforts.......
