To find the roots/zeros, set equal to and solve.

Rewrite as .

Since both terms are perfect squares, factor using the difference of squares formula, where and .

Apply the product rule to .

If any individual factor on the left side of the equation is equal to , the entire expression will be equal to .

Set the first factor equal to .

Set the equal to .

Subtract from both sides of the equation.

Set the next factor equal to .

Set the equal to .

Add to both sides of the equation.

The final solution is all the values that make true. The multiplicity of a root is the number of times the root appears.
