Question
Solving Equations involving Radicals
The equation obtained by raising both sides of an equation may have a
solution that is not a solution of the original equation.
To solve equations involving radicals:
1. Raise both sides of the equations to the appropriate power.
2. Solve the equation that arises.
3. Check for extraneous solutions.
Note: In solving equations, we check for extraneous solutions whenever
we raise both sides of an equation to a power.
Theorem
Let A and B be expressions and let n € N.
The solution set of the equation A = B is a subset of the
solution set of A" = B".
