What is the product of -2x^3+x-5 & x^3-3x-4
Please show all work and explain

- 2 + 7 + 3x³ - 3x² + 11x + 20

Step-by-step explanation:

Given

(- 2x³ + x - 5)(x³ - 3x - 4)

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

- 2x³(x³ - 3x - 4) + x(x³ - 3x - 4) - 5(x³ - 3x - 4) ← distribute the 3 parenthesis

= - 2 + 6 + 8x³ + - 3x² - 4x - 5x³ + 15x + 20 ← collect like terms

= - 2 +7 + 3x³ - 3x² + 11x + 20

the aswere is the one with all 8's and the second one is with the 10,8 and 6
