Radical Equations

Defn A radical equation is an equation with one or more variables inside the radical.

**When solving radical equations, we must check for extraneous solutions.**

Problems where extraneous solutions may exist:

1) When solving rational equations (section 6.4)
2) When solving radical equations

Ex 1 Solve for x.

This leads to…

If , then , for any natural number n. Ex 2 Solve and check your work.
