Question

Which expression is factored form? X^2+14x+48

A) (x-8)(x-6)
B) (x+6)(x-8)
C) (x+8)(x-6)
D) (x+6)(x+8)

Answer 1

D

Explanation:

given x² + 14x + 48

Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (+ 14)

The factors are + 6 and + 8, since

6 × 8 = 48 and 6 + 8 = 14

x² + 14x + 48 = (x + 6)(x + 8) ← in factored form
