Скачать или смотреть Rational Equations: Practice

This video continues with the idea of solving rational equations by looking at a couple example problems. The general strategy is to first determine which values of the variable lead to division by zero and write that the variable cannot equal those values. The next step is to get the variable terms or expressions out of the denominator by multiplying each side of the equation by whatever is in the denominator. The resulting equation will usually be a polynomial which can be solved by the usual techniques.
