Dr. Fraser teaches you how to Solve Radical Equations in this new lecture. You begin with an overview of radical equations before diving into the steps of solving a radical equation: isolating the radical and squaring both sides. After covering extraneous solutions, you are ready to tackle the four extra examples at the end.
equation is an equation that contains radicals with variables in
To solve a radical
equation, isolate the radical on one side of the equation and then
square both sides of the equation. This will eliminate at least one
radical. If a radical remains in the new equation, repeat the
solution is a value which produces a negative radicand in one or
more of the radicals in the original equation. Check all potential
solutions in the original equation. Exclude extraneous values from
the solution set.
