Question

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

Answer 1

Answer:

A

Step-by-step explanation:

We need to find two numbers that have a sum of 5 and a product of 6. These numbers are 2 and 3 so x² + 5x + 6 factored is (x + 2)(x + 3). Since x + 2 is a factor the answer is A.

Answer 2

Answer:

$\mathrm{A}$

Step-by-step explanation:

$x^2 + 5x + 6$

$x^2+3x+2x+6$

$x(x+3)+2(x+3)$

$(x+2)(x+3)$
