Solving Quadratic Equations by Factoring

To solve equations, there are several ways.  By factoring, completing the square, the formula, or graphing, etc.- However, all methods start with setting the equation equal to zero, which is very important.

I’d like to show the method by factoring in this video.

There are three types of solutions,

  • one solution which is often called double root.
  • Two solutions with real numbers or imaginary number cases.
