Here is a recap of today's classes:
- Algebra One - We looked at a third way of solving systems of equations, ELIMINATION. We will continue working on problems using elimination tomorrow.
- Use this video to review for class tomorrow: Solve by Elimination
Algebra Two- We reviewed what a determinate of a quadratic equation is, and what it tells us about the quadratic.
- Here is a nice little review of what we looked at today! Quadratic formula and the discriminant
