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)

D

Step-by-step 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
