5-5 Standard Form of Quadratics, Their Zeros and Graphs

Watch a video on Solving a Quadratic by Factoring.

This expression is NOT in Standard form of a Quadratic.

Using the additive inverse of 21 gives you:

Factoring and using the ZERO-Product Property yields the following for zero's and solutions!

Some expressions (when b=0)

Solve by Graphing

approximate the x-intercepts from the graph

You can use the Desmos Parabola in vertex form to help your understanding of a, h, and k, (but you need to be able to do this own your own!)
Do you OWN it?
