Today we took what we know about factoring (GCF and trinomials) to solve quadratic equations algebraically, using the Zero Product Property, which is a fancy name for what we know intuitively about two numbers multiplying together to be zero.
Here are the marked class slides.
Here is the homework: page 272 in the textbook , #13-15 and #38-43
Also, Delta Math is due on Friday, as usual.
