Introduction to Quadratic Equations

What you’ll learn to do: find the solutions to quadratic equations.

An equation containing a second-degree polynomial is called a quadratic equation. For example, equations such as [latex]2{x}^{2}+3x - 1=0[/latex] and [latex]{x}^{2}-4=0[/latex] are quadratic equations. They are used in countless ways in the fields of engineering, architecture, finance, biological science, and, of course, mathematics.

Specifically, in this section you’ll learn how to solve quadratic equations using:

  • factoring and
  • the quadratic formula
