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! Reminder!!!

8. get one radical on each side of =

9. Set quadratic equation to 0 get one radical on each side of = FOIL

11. Set quadratic equation to 0 get one radical on each side of = FOIL

14. -2 -2 -2 FOIL get one radical on each side of = Divide
