Solving Radical Equations and Inequalities

  • To solve a radical equation, raise both sides of the equation to the power equal to the index of the radical. This will eliminate at least one radical. If a radical remains in the new equation, repeat the process.

  • Always check for extraneous solutions – values for which one or more radicals in the original equation have a negative radicand. Exclude such values from the solution set.
