Which of the binomials below is a factor of this trinomial?

x2 + 2x-35

A. x+7

B. x+1

C. x-1

D. X-7

A

Step-by-step explanation:

Given

x² + 2x - 35

Consider the factors of the constant term ( - 35) which sum to give the coefficient of the x - term ( + 2)

The factors are + 7 and - 5, since

7 * - 5 = - 35 and 7 - 5 = + 2, thus

x² + 2x - 35 = (x + 7) (x - 5) ← in factor form

With x + 7 as a factor → A
