Bellwork reviewed finding the coordinates of the Vertex and solving quadratic equations by factoring and using square roots.
The remainder of the period we discussed working backwards: Turning solutions back into the original quadratic equation (Standard Form).
We also worked on a couple of “story problems” that could be solved with quadratic equations.
The practice sheet from sec 5-5 is due tomorrow.
Hwk #19 is due tomorrow: Pages 270-271, Problems 2, 3, 5-7, 10, 11, 13, 14, 51, 52
