Question

Sari is factoring the polynomial 2x2+5x+3. If one factor is (x+1), what is the other factor?

Answer 1

Answer:

(2x + 3)

Step-by-step explanation:

$2x^2 + 5x + 3$

Factor by grouping:

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

$2x(x + 1) + 3(x + 1)$

$(2x + 3)(x + 1)$

Then, take the factor that isn't (x + 1) so you get:

$(2x + 3)$

which is the answer.
