Question

3x2 +16× +5 factor for the trinomial

Answer 1

(x + 5) (3x + 1)

Explanation:

Use the AC method.

3 × 5 = 15

Factors of 15 that add up to 16 are +1 and +15.

15/3 = 5/1, and 1/3 = 1/3

Constants are the numerators, coefficients are the denominators.

(x + 5) (3x + 1)

Use FOIL to check answer.

3x² + x + 15x + 5

3x² + 16x + 5
