Add or subtract the equations to eliminate one variable, and then solve for the other variable. 2. Substitute the value into either original equation to find the value of the eliminated variable. 3.
Solve equations involving square roots by first isolating the radical and then squaring both sides. Squaring a square root eliminates the radical, leaving us with an equation that can be solved using the techniques learned earlier in our study of algebra.

LESSON A radical equationis an equation that contains a variable within a radical. You can square both sides of an equation, and the resulting equation is still true.
Answer to Solve the following radical equations. Be sure to show that you checked your solutions. What do you notice when checking.
A basic strategy for solving radical equations is to isolate the radical term first, and then raise both sides of the equation to a power to remove the radical. The reason for using powers will become clear in a moment. This is the same type of strategy you used to solve other, non-radical equations—rearrange the expression to isolate the variable you want to know, and then solve the.
CHAPTER 3 Section 3.7: Solving Radical Equations Page 174 Example 5. Solve the equation. 3 8 0 38 xx xx xx Even index, we will have to check all results Isolate first root by adding x to both sides Square both sides 38xx 22 Evaluate exponents 38 33 82 22 xx xx x Solve the equation Subtract 3x from both sides Divide both sides by 2 4 x Need to check result in original equation 3(4) 8 4 0.

Students learn to solve square root equations by first isolating the square root, then squaring both sides of the equation. Students also learn to solve cube root equations by first isolating the cube root, then cubing both sides of the equation. Make sure to check the solution in the original equation. If it does not check, then the answer is the null set.
