Solving quadratics can be difficult. Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots, or using the quadratic formula. The cool thing is that solving quadratic equations by completing the square will always work when solving quadratic equations, and the technique is a good tool to have in your math tool belt.

How Do You Factor Quadratic Equations?


To solve a quadratic equation by factoring, you set one side of the equation equal to zero and use the zero product property to factor the equation. Other ways to factor a quadratic equation are completing the square, using square roots, and using the quadratic formula.

Solving quadratic equations using square roots works best under special circumstances. If your equation does not have a “b” term this technique may be a good one for you to try. Keep in mind that if this technique does not work well with your equation, there are a number of other techniques that can be used instead.

There are several ways to solve quadratic equations, one of which is factoring. When we solve quadratic equations by factoring we set one side of the equation to zero, and then factor the quadratic equation, so we can use the zero product property to determine where x = 0.

In addition to solving quadratic equations by factoring, we can also use square roots, the completing the square method, or the quadratic formula.
