# Day 16 – Equation Solving using Zero Product Rule

Assignment Day 16:

1. MathZone: Assignment 5 – Factoring and Equation Solving (Days 14-16), due 11/1/11.
2. Work on your group project!

TEXT: Intermediate Algebra by Miller, O’Neill and Hyde

Note: The problems assigned in the book below are NOT required and will not be collected.  However, they are quite similar to the problems in the MathZone assignment for this section.  They are a good resource if you wish to do additional problems for practice.

It needs some concentration

We just learned this in class. I find it to be very easy. One thing that i reccomend is not forgetting to set each equation equal to zero. One thing i learned today was that the reason for not writing the final answer in parenthesis was because there will only be “x” values, not “y’s” so you would have to put the answer as in sets. For eaxample, if x=2, x=3, the answers would be written as {2,3}, not as (2,3) because there is no “y” values.
