Again, we call this an extraneous solution as we did when we solved rational equations. A radical expression is simplified if its radicand does not contain any factors that can be written as perfect powers of the index. We typically assume that all variable expressions within the radical are nonnegative. This allows us to focus on simplifying radicals without the technical issues associated with the principal \(n\)th root.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 any equation that contains one or more radicals with a variable in the radicand. Following are some examples of radical equations, all of which will be solved in this section: √x − 1 = 5 √2x − 5 + 4 = x 3√x2 + 4 − 2 = 0. In general, when we solve radical equations, we often look for real solutions to the equations. So yes, you are correct that a radical equation with the square root of an unknown equal to a negative number will produce no solution. This also applies to radicals with other even indices, like 4th roots, 6th roots, etc. Solution. First, isolate the radical on one side of the equation by adding 2 to both sides and dividing by 3 to simplify. 33√x − 8 − 2 = -14 33√x − 8 = -12 3√x − 8 = -4.

We can solve it by multiplying both sides by the denominator, but we have to look out for extraneous solutions in the process. Created by Sal Khan.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 ...If the radical is a square root, then square both sides of the equation.
