A.CED.2

• I can write and interpret rational and radical equations (in two or more variables) mathematically and in context, graphically and algebraically.

A.REI.2

• I can solve radical and rational equations in one variable.
• I can give examples showing how extraneous solutions may arise when solving rational and radical equations.

F.IF.7, 7b, 7d
