In this lecture you will learn how to Solve Radical Equations and Inequalities. After a brief overview of Radical Equations, you will move into Extraneous Roots, Eliminating nth Roots, and Radical 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.
