## Quadratic Equations II **What is a quadratic equation?** A quadratic equation is a polynomial equation of degree 2, written in the form $ax^2 + bx + c = 0$, where $a \neq 0$. **Key Points** 1. The standard form is $ax^2 + bx + c = 0$. 2. If $\alpha$ and $\beta$ are the roots, then sum $= -\frac{b}{a}$ and product $= \frac{c}{a}$. 3. To form an equation from roots: $x^2 - (\alpha + \beta)x + \al [Preview only]
