Solving Radical Equations What is a radical equation? An equation that contains a radical expression with a variable in the radicand.
Inverse Operations How would you solve the following equation? Solve by taking the SQUARE ROOT. Why? = 9 Square roots and Squaring are inverse operations… they “undo” each other! x = 3,-3
So… consider this: How could you solve for x now? Solve by doing the inverse operation: SQUARING!
A Refresher on Inverses (opposites): Opposite of Multiply is ____________ Opposite of Add is ____________ Opposite of Divide is ____________ Opposite of Subtract is ____________ Opposite of squaring is ____________ Opposite of square rooting is ____________
Steps to Solving Radical Eq’s: Isolate the radicand – get the radicand on one side and all other terms on the other. Square both sides of the equation Solve for x CHECK YOUR ANSWER!!!!
