Bell Work

Could you solve #3? You could NOT use basic math to solve for x. You have to use something called the QUADRATIC FORMULA.

Quadratic Formula * You will learn how to solve for “x” using the quadratic formula. * You will also review how to simplify radical expression during the process.

Practice Solving

Practice Simplifying Radicals Log onto our gizmos to practice simplifying radicals again. You must go through at least 10 examples of simplify radicals. Make sure that you answer the assessment questions at the bottom of the gizmo.
