Algebra: Rational Equations and Inequalities
Rational Equations and Inequalities
Knowing how to add or multiply fractions is all well and good, but what happens when they start popping up in other places? What do you do when an equation contains fractions? How in the world do you solve an inequality featuring fractions? How are you supposed to react if a fraction sneaks into your house when you're asleep and tries to steal that jar you dump your pocket change into? All these questions (with the exception of the last) are answered in this section.
