4. Mon 1/11 Lesson 6 – 5 Learning Objective: To solve square root equations Hw: Lesson 6 – 5 WS 1

5. Algebra II

6.  To solve square root equations  To solve radical equations

7.  Get radical alone  OR get one radical on each side of =  “Undo” the radical  May have the “undo” more than one radical  Solve for the variable  Plug back into ORIGINAL equation to check for EXTRANEOUS SOLUTIONS!

10. x + 3 = 8 x = 5 Or x + 3 = -8 x = -11 MUST BOTH!

13. x + 1 = 8 x = 7 OR x + 1 = -8 x = -9
