**Problem 4: Solving the Polynomial Equation**

Solve the equation: 

\[ 2x^3 - 3x^2 - 11x + 6 = 0 \]

**Given:** 

-2 is a zero of 

\[ f(x) = 2x^3 - 3x^2 - 11x + 6 \]

**Explanation:**

This problem involves finding the roots of a cubic polynomial equation. The information that -2 is a zero means that \( x = -2 \) is one of the roots of the polynomial. The task is to use this information to solve the equation by finding all roots.
