The Khan Academy assignment is due by the 23rd and covers simplifying rational expressions. Radical Test 2 is on Wednesday and a calculator is recommended. Class work 4.10 is optional for extra credit if all work is shown. Today's class work closely resembles the test, so students should work the problems and bring questions to class tomorrow. The document provides review information and examples for the Radical Test 2. It includes topics on the distance formula, midpoint formula, a variation of the midpoint formula, the Pythagorean theorem and finding missing values given endpoint and midpoint coordinates.
