Question

Which equals the product of (x – 3)(2x + 1)?

2x² – 7x-3
2x² – 5x-3
3x-2
0 6x²

Answer 1

2x² - 5x - 3

Explanation:

Given

(x - 3)(2x + 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 1) - 3(2x + 1) ← distribute parenthesis

= 2x² + x - 6x - 3 ← collect like terms

= 2x² - 5x - 3
