-4= -4x to the third power - 4x to the second power.

x = 0.754878...

Step-by-step explanation:

Hi there! I'm glad I was able to help you solve this math problem!

First, you'll want to subtract -4x^3 - 4x^2 from each side of the equation. This cancels out the right side of the problem, leaving us with a problem that equals zero.

-4 - (-4x^3 - 4x^2) = -4x^3 - 4x^2 - (-4x^3 - 4x^2)

4x^3 + 4x^2 - 4 = 0

Next, we use the cubic formula to solve for x. You can use a calculator to do this part for you!

x = 0.754878... is your answer.
