To solve an equation with a root, (we'll assume here a square root,) one common solving technique is to square both sides. If there are factors that are not roots, we need to square them as well. This will work when the root is multiplied by a constant- if it is added or subtracted to a root, you will need to use binomial expansion or FOIL'ing to square both sides.
