We continued our work with quadratics today by taking a look at another tool to solve for x. We have used factoring, the quadratic formula, and using radicals so far. Today's skill was completing the square. We went through 4-5 examples of how to complete the square on various quadratics. Our goal today was to complete the square while working with a leading coefficient of 1. After the examples were complete, the students then got to work on their assignment.

### Honors Algebra 2; 3/18

Today was the first day of our unit on quadratics. We reviewed the concept of how to solve quadratics by factoring and also using square roots. We then introduced the use of the quadratic equation as another tool to solve quadratics. We went through examples involving both real and imaginary solutions before the students got started on their assignment.
