Question

What’s does X-3 times X+5 equal

Answer 1

x² + 2x - 15

Explanation:

Given

(x - 3)(x + 5)

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

x(x + 5) - 3(x + 5) ← distribute both parenthesis

= x² + 5x - 3x - 15 ← collect like terms

= x² + 2x - 15
