Concepts for May 16th

Algebra I

Today we discussed
Today we discussed how to use the method of completing the square to solve quadratic equations.  The goal is to get a perfect square trinomial so that we can take the square root of both sides of the equation to get the solution.

If the leading coefficient is more than 1, see example below.

We did not have time to work on these in class.

Also see video tutorial below for another example worked out.
