This week I learned how to solve quadratic equations using square roots.

Here is a common question:

This question asked me to solve the equation by completing the square. The first thing you need to do in this question is make it a square. You figure out the square by chopping the middle term in half then square it . You add into the equation by making it a zero pair. Then you can solve for x by simplifying the part of the equation that is in brackets to and add together the part not in brackets to get . After you have done this you move to the other side of the equation and square root the whole thing. Then you can move to the other side. Once you have done this you have simplified for x.
