This equation is not quadratic, because it contains a term involving x³. However, we can solve it by using factoring. First we get 0 on the right side by subtracting 17x2 from both sides. Then we factor the polynomial on the left side and use an extension of the zero-factor property.

## Solving Polynomial Equations by Factoring

### Example Problem: 

**Solve:** \( 6x^3 + 12x = 17x^2 \)

This equation is not quadratic because it contains a term involving \( x^3 \). However, we can solve it by using factoring. First, we get 0 on the right side by subtracting \( 17x^2 \) from both sides. Then, we factor the polynomial on the left side and use an extension of the zero-factor property.

**Step-by-Step Solution:**

1. **Rewrite the equation to set one side to 0:**
   \[
   6x^3 + 12x - 17x^2 = 0
   \]

   This is achieved by subtracting \( 17x^2 \) from both sides:
   \[
   6x^3 + 12x - 17x^2 = 17x^2 - 17x^2 \implies 6x^3 - 17x^2 + 12x = 0
   \]

2. **Factor out the greatest common factor (GCF):**
   \[
   x(6x^2 - 17x + 12) = 0
   \]

3. **Factor the trinomial:**
   \[
   x(2x - 3)(3x - 4) = 0
   \]

4. **Apply the zero-factor property:**
   If \( x(2x - 3)(3x - 4) = 0 \), then at least one of the factors must be zero.

   \[
   x = 0 \quad \text{or} \quad 2x - 3 = 0 \quad \text{or} \quad 3x - 4 = 0
   \]

5. **Solve each equation:**
   - \( x = 0 \)
   - \( 2x - 3 = 0 \implies 2x = 3 \implies x = \frac{3}{2} \)
   - \( 3x - 4 = 0 \implies 3x = 4 \implies x = \frac{4}{3} \)

**Solution Set:**

The solutions are \( 0 \), \( 3/
