# Polynomial Division and Rational Expressions Topics

## Polynomial Division and Rational Expressions explanations, examples, practice problems. Ready? Let’s do this.

#### Polynomial Division

Polynomials have tons of similarities to integers, and throughout this section we'll be coming back a lot to the integer analogy to make our points. We'll look at polynomial division in a few diffe...

#### Rational Expressions

Rational expressions are nothing to be afraid of. Don't let the bared fangs and red, glowing eyes fool you. Despite the scary drooling, they're only a particular type of expression. The eyes are...

#### More Polynomial Division

Back for more? We knew you couldn't stay away.Now that we know what rational expressions are, we can investigate general polynomial division. Any polynomial division problem can be written as a r...

#### Simplifying Complex Rational Expressions

A complex rational expression is a rational expression in which the numerator and/or the denominator are rational expressions. In other words, a complex rational expression is a nasty-looking rat...

#### Equations Involving Rational Expressions

Solving an equation that contains rational expressions is similar to solving any old equation that has fractions in it. In fact, if the variable only occurs in numerators, we actually are solving...

#### In the Real World

Polynomials and rational expressions are used to express properties of the physical world, like how gravity works. If you need a funnier example of gravity at work (or not at work), check this ou...
