**11-2 Solving Quadratic Equations By Graphing**

2
Quadratic Equation An equation in which the value of the related quadratic function is 0. You have used factoring to solve equations like this. You can also estimate the solutions to this equation using graphing.

3
**Solutions of a quadratic Equations**

Solutions are called roots Found by finding the x-intercepts or Zeros of the function. It is possible for a function not to have a Zero.
