125. 130. 19 20 Part I: The Questions Chapter 3 Solving Radical and Rational Equations A radical equation is one that starts out with a square root, cube root, or some other root and gets changed into another form to make the solving process easier. The new form may have solutions that don’t work in the original equation, but this method is still the easiest. A rational equation is one that involves a fractional expression — usually with a polynomial in the numerator and denominator. These equations are also changed in order to solve them, and they also carry the concern of an extraneous or false root.
