Solving Radical Equations Follow the following four steps to solve radical equations. 1. Isolate the radical expression.2. Square both sides of the equation: If x = y then x2 = y2.3. Once the radical is removed, solve for the unknown.4. Check all answers. Solve. A) B) C) D) Show/Hide AnswerA) Incorrect. Check your answer. If you substitute into the equation, you get , or . This is not correct. Remember to square both sides and then solve for x. The correct answer is . B) Incorrect. It looks like you squared both sides but ignored the +22 underneath the radical. Remember to include the entire binomial when you square both sides; then solve for x. The correct answer is . C) Correct. Squaring both sides, you find becomes , so and . D) Incorrect. It looks like you only squared the left side of the equation. Remember to square both sides: , which becomes . Now solve for x. The correct answer is .
