How to solve radical equations

The solution x = -8 is extraneous to the original equation √ (4x + 41) = x + 5. However, it is the solution to the equation -√ (4x + 41) = x + 5. The expression under the radical is same in both equations, so in terms of keeping the radicand non-negative, the value -8 is OK. If we take the function y = √ (4x + 41), then -8 would be a ...

1. Isolate the radical term. The first step to solving a radical equation is to move the radical term to stand alone on one side of the equation. Move all other terms to the opposite side. In this step, if possible, combine any other like terms that may exist. [2] Consider the sample problem.The domain is usually defined for the set of real numbers that can serve as the function's input to output another real number. If you input any number less than 4, the output would be a complex number, and would not count toward the domain.

Combine the radicands into one radical, and reorganize to see if there are any cubes. − 14 3√2 ⋅ 32 ⋅ 3 ⋅ 5 = − 14 3√2 ⋅ 33 ⋅ 5. Apply the cube root to 33, and simplify the radicand. − 14 ⋅ 33√2 ⋅ 5 = − 423√10. A "radical" equation is an equation in which there is a variable inside the radical sign. Four steps to solve equations with radicals. Step 1: Isolate the radicals to left side of the equal sign. Step 2: Square each side of the equation . Step 3: Solve the resulting equation . Step 4: Check all solutions . Equations with one radical Step 1 : Raise both sides of the equation to the nth power to get rid of the radical. For example, if you have square root, square both sides of the equations. If you have cube root, raise both sides of the equation to the 3 rd power. Step 2 : Use algebraic techniques to solve for the variable. Solve the following equations and check the answers :of the equation you must do to the other side. Example: x=7 ⇒square both sides ⇒ ( ) =( )2 ⇐ 2 x 7 The square and square root cancel out on the left. So, x=(7)2 ⇒ x=49Done! Note: The radical must be isolated on one side of the equal sign before you can square both side. Example: Solve 2 x−5+3=21 The radical is not isolated.Often equations have more than one radical expression.
