Solving Quadratic Equations using the Square Root Property

We will start with an example that contains only one term with the variable we are trying to solve for.



 

In this example there is an x variable that is squared on only one side of the equation

Here is the same example worked out using a Livescribe Pulse Smart Pen



 

In this next example there is only x variable that is contained inside a perfect square binomial

 

 

 

Here is the same example worked out using Elluminate's white board and Jing to capture the video.


 

In this example there is only one x variable that is contained inside a perfect square binomial

In the last two examples the quadratic only had one term with the variable we were trying to solve for inside a perfect square binomial. In the next section we will learn how to "complete the square" of a quadratic with both an x-squared term and an x-term to create a perfect square binomial. Every quadratic will be able to be solved using the "complete the square method".
