We have done a lot of work with solving quadratic equations and looking at contextual situations. But what if we are just given a solution or //x//-intercept or root, how do we write an equation from those? In order to write the equation we will simply work backwards. We will use the steps of solving by factoring and work backwards. Below is an example of solving by factoring from **Target SQE A**. You can always refer to that section if you need more review.

Let's look at a few examples to see how to write a quadratic equation from the solutions. Let's try another example, watch the video below. media type="custom" key="27728261" media type="custom" key="27728263" **Quick Check - Solving Quadratic Equations - Target D - Write Quadratics** 1) Write the quadratic equation that has the following roots. x = -1 and x = 2. 2) Write the quadratic equation that represents the following graph.
