Question

Select all the solutions of x^3 + 2x^2 - 9x = 18.

Answer 1

To find the solutions of the equation x^3 + 2x^2 - 9x = 18, you can use numerical methods like Newton-Raphson or graphing the equation to find the approximate solutions.

Step-by-step explanation:

To find the solutions of the equation x^3 + 2x^2 - 9x = 18, we can rearrange it as x^3 + 2x^2 - 9x - 18 = 0. This is a cubic equation. We can factor it or use numerical methods to find the solutions.

Factoring the cubic equation may not be easy, so we can use numerical methods like the Newton-Raphson method or graphing the equation to find the approximate solutions. Alternatively, we can use a calculator or software to solve the equation.
