Question

Select one of the factors of the quadratic expression.

x2 + 5x - 14

Answer 1

(x + 7) or (x - 2)

Explanation:

Given

x² + 5x - 14

Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (+ 5)

The factors are + 7 and - 2, since

7 × - 2 = - 14 and 7 - 2 = + 5, hence

x² + 5x - 14 = (x + 7)(x - 2)
