Answer:

D) 2x^2 + 5x - 3

Explanation:

Multiply everything in the first set of parentheses by everything in the second set of parentheses. x(2x) + x(-1) + 3(2x) + 3(-1) = 2x^2 - x + 6x - 3. Combine like terms. The correct answer is 2x^2 + 5x - 3.

(x + 3)(2x - 1)

2x^2 - x + 6x - 3

=2x^2 + 5x - 3

Hope this helps!!!
