Solve Systems using ISS - Isolate, Substitute, Solve. Watch the first video and take notes in your packet on page 17. The second video will help you practice the problems on page 20. Watch out for problem 10, the x's cancel out from both sides. When that happens, remember that true is infinite solution and false is no solution. Check your answers when you finish practicing the problems on page 20.
Today, I have two videos for you to watch on solving quadratics using the Quadratic Formula. The first video will show you examples when your answers are rational and the second video will show you what to do when your answers are irrational. Next, you have a Deltamath assignment titled - "Alg-Solving Quadratics using Quadratic Formula".
