• How do you solve a radical equation?
• How do you solve sqrt(2x - 3) + 3 = 6?
• How do you solve sqrt(5x - 9) = sqrt(2x - 3)?
• How do you solve a radical equation if there are square roots on both sides?
• How do you solve sqrt(x + 5) = sqrt(x) + 1?
• Why can you raise both sides of an equation to the same power?
• What are the steps for solving a radical equation?
• Why do you have to get a square root by itself in an equation before squaring both sides?
• Why is it important to check solutions to a radical equation?
• Why do the solutions to radical equations not always work in the original equation?
• What do you do if you can't isolate both radicals in an equation?

This lesson goes through some more difficult problems involving square roots in equations. The radicals must be isolated first, and then both sides of the equation are squared in order to find the solutions. Some equations even have radicals on both sides of the equation. The very important step of checking the solutions is shown for each problem as well.
