Today we learned the final method for solving a quadratic equation, the quadratic formula. I showed them how to use it to solve an equation. See some more examples here. We did some examples on the board, then they used the examples to help them with the homework. We will begin our review for next Thursday's semester test on Friday. Also, for extra credit, students can derive the quadratic formula from 0=ax^2+bx+c by completing the square.Homework:
