11 mar 2023 · To solve radical equations, which are any equations where the variable is under a square root, start by isolating the variable and radical on one side of the equation. Then, to undo the radical, square both sides of the equation.
Key Steps to Solve Radical Equations: 1) Isolate the radical symbol on one side of the equation. 2) Square both sides of the equation to eliminate the radical symbol. 3) Solve the equation that comes out after the squaring process. 4) Check your answers with the original equation to avoid extraneous values or solutions
How to Solve Radical Equations. Solving a radical equation simply means finding the value of the variable. The variable in a radical equation is under the radical sign. Thus, exponent rules and fundamental algebraic principles must be followed in order to solve radical equations.
A Radical Equation is an equation with a square root or cube root, etc. We can get rid of a square root by squaring (or cube roots by cubing, etc). Warning: this can sometimes create "solutions" which don't actually work when we put them into the original equation.
Solve a Radical Equation With One Radical. Isolate the radical on one side of the equation. Raise both sides of the equation to the power of the index. Solve the new equation. Check the answer in the original equation. When we use a radical sign, it indicates the principal or positive root.

31 paź 2021 · How to: Solve a Radical Equation. Isolate a radical. Put ONE radical on one side of the equal sign and put everything else on the other side. Eliminate the radical. Raise both sides of the equal sign to the power that matches the index on the radical. This means square both sides if it is a square root; cube both sides if it is a cube root; etc.
