Question

The expression below is the factorization of which of the following trinomials?

(2x+7)(x+5)

A.) 2x^2 + 17x + 35

B.) 2x^2 + 12x + 35

C.) 2x^2 + 10x + 35

D.) 2x^2 + 2x +35

 

Answer 1

The expression (2x + 7)(x + 5)

= (2x)(x) + (2x)(5) + 7(x) + 7(5)

= 2x² + 10x + 7x + 35

= 2x² + 17x + 35

Option A is correct.
