1. **State the problem:** Simplify or analyze the expression $180 - 2w^2 + 3w$.
2. **Identify the type of expression:** This is a quadratic expression in terms of $w$ because it contains a $w^2$ term.
3. **Rewrite the expression in standard form:**
$$-2w^2 + 3w + 180$$
4. **Explain the components:**
- The coefficient of $w^2$ is $-2$ (which means the parabola opens downward if graphed).
- The coefficient of $w$ is $3$.
- The constant term is $180$.
5. **If asked to find roots or factor, use the quadratic formula:**
$$w = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a = -2$, $b = 3$, and $c = 180$.
6. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = 3^2 - 4(-2)(180) = 9 + 1440 = 1449$$
7. **Find the roots:**
$$w = \frac{-3 \pm \sqrt{1449}}{2(-2)} = \frac{-3 \pm \sqrt{1449}}{-4}$$
8. **Interpretation:** Since the discriminant is positive, there are two real roots.
**Final answer:** The expression is a quadratic with two real roots given by
$$w = \frac{-3 \pm \sqrt{1449}}{-4}$$
