Answer:
A. (2x + 1)(x + 5).
Step-by-step explanation:
Factor 2x^2 + 11x + 5
Use the ac method:
2 * 5 = 10.
We need 2 numbers whose product is + 10 and whose sum is +11.
They are + 10 and +1 so we write:
2x^2 + 10x + x + 5
Factor by grouping:
= 2x(x + 5) + 1(x + 5)
The x + 5 is common so we get:
(2x + 1)(x + 5).
