Question

Multiply the polynomials.

Answer 1

In the equation is that x squared?

Answer 2

Answer:

C) x³ -4x² - 24x + 21.

Step-by-step explanation:

Given : (x – 7)(x² + 3x – 3).

To find : Multiply the polynomials.

Solution : We have given  (x – 7)(x² + 3x – 3).

Distributes x over (x² + 3x – 3) and  -7 over (x² + 3x – 3).

Then

x (x² + 3x – 3) -7(x² + 3x – 3).

x³ + 3x² -3x - 7x² - 21x +21.

Combine like terms

x³ + 3x² - 7x² -3x -21x + 21.

x³ -4x² - 24x + 21.

Therefore, C) x³ -4x² - 24x + 21.
