13. Which of the options represents the factored form of x2 + 5x + 6? A (x + 2)(x+3) C. (x + 4)(x + 2) B. (x + 5)(x + 1) D. (x+3)(x + 3)​

Answer:

A

Step-by-step explanation:

I THINK YOU SHOULD USE A "FOIL" METHOD

(x+2)(x+3)

=X²+3+2x+6

=x²+5x+6

(x + 2)(x + 3)

Solution:

x² + 5x + 6 = 0

(x + 2)(x + 3) = 0

x + 2 = 0 x + 3 = 0

x = -2 x = -3

Because, 2 + 3 = 5 and 2 x 3 = 6
