Solve the polynomial.

X^3 + 4x^3 - 11x - 30 = 0

The answer is approximately 2.21456

Step-by-step explanation:

1. You simplify your equation to:

5x^3-11x-30=0

2. Now you can use the Newton Raphson method to solve this problem.

The Newton Raphson method can be used by calculating x + 1 until its delta turns into something below 0.00001, and the x value is your answer.
