Question

Express the product of 2x^2 + 6x - 8 and x + 3 in standard form

Answer 1

2x³ + 12x² + 10x - 24

Explanation:

Answer 2

2x^3 + 12x^2 + 10x - 24

Explanation:

Product means multiply

So

(2x^2 + 6x - 8) (x + 3)

= (2x^2 * x) + (2x^2 * 3) + (6x * x) + (6x * 3) - (8 * x) - (8 * 3)

= 2x^3 + 6x^2 + 6x^2 + 18x - 8x - 24

= 2x^3 + 12x^2 + 10x - 24
