## Quadratic Equations I **What is a Quadratic Equation?** A quadratic equation is a polynomial equation of the second degree, meaning it contains at least one term where the variable is squared. Its standard form is $ax^2 + bx + c = 0$, where $a, b, c$ are real numbers and $a \neq 0$. **Key Points** 1. The highest power of the variable in a quadratic equation is 2. 2. The coefficients $a, b, c$ a [Preview only]
