Rational expressions must be simplified down to the same simplest factors. This is a fairly easy process if the same factor is a single term factor, but it gets a little more detailed if the factor includes many terms. Here's what you should do, depending on the type of rational expression you're dealing with.

Factors of a number are numbers that can be multiplied to get that number. Another way of looking at it is that every number is the product of multiple factors. Learning how to factor – that is, breaking down a number into its component factors – is a mathematical skill that is used not only in basic arithmetic but also in algebra, calculus, and others.

A complex fraction is a fraction in which the numerator, denominator, or both also contain a fraction. For this reason complex fractions are sometimes referred to as "stacked fractions". Simplifying complex fractions can be easy or difficult, depending on how many numbers are in the numerator and denominator, whether one of the numbers is a variable, or the complexity of the variable number.

The Punnett quadrilateral is a visual device used in the science of genetics to determine which combinations of genes may occur at conception. A Punnett square is made of a simple square grid divided into a 2x2 (or larger) grid. With this grid, and knowledge of the genotypes of both parents, scientists can discover potential gene combinations for offspring and possibly even know some inherited traits.
