1. **State the problem:** Solve the equation $2(2x - 3) - (6x - 9) = 2x^2$ for $x$.
2. **Apply the distributive property:**
$$2(2x - 3) = 4x - 6$$
$$-(6x - 9) = -6x + 9$$
So the left side becomes:
$$4x - 6 - 6x + 9$$
3. **Combine like terms on the left side:**
$$4x - 6x = -2x$$
$$-6 + 9 = 3$$
So the equation is:
$$-2x + 3 = 2x^2$$
4. **Rewrite the equation to standard quadratic form:**
$$2x^2 + 2x - 3 = 0$$
5. **Use the quadratic formula:**
For $ax^2 + bx + c = 0$,
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
Here, $a=2$, $b=2$, $c=-3$.
6. **Calculate the discriminant:**
$$b^2 - 4ac = 2^2 - 4(2)(-3) = 4 + 24 = 28$$
7. **Find the roots:**
$$x = \frac{-2 \pm \sqrt{28}}{2 \times 2} = \frac{-2 \pm 2\sqrt{7}}{4}$$
8. **Simplify the fraction:**
$$x = \frac{\cancel{-2} \pm \cancel{2}\sqrt{7}}{\cancel{4}} = \frac{-1 \pm \sqrt{7}}{2}$$
9. **Final answer:**
$$x = \frac{-1 + \sqrt{7}}{2} \quad \text{or} \quad x = \frac{-1 - \sqrt{7}}{2}$$
