Suppose that R(x) is a polynomial of degree 8 whose coefficients are real numbers. Also, suppose that R(x) has the following zeros.-4, 6, 8, -1-4i

Subtract 3 from both sides.

3 5^v/(x + 2)^3 = 24

Divide both sides by 3.

5^v/(x + 2)^3 = 8

Raise both sides to the power of 5 to cancel out the 5 square root.

(x + 2)^3 = 32768

Take the cube root of both sides to cancel the power of 3.

x + 2 = 32

Subtract 2 from both sides.

x = 30
