Factoring equations in math is sometimes called "pulling out numbers." This means taking out numbers that every term have in common to make the question easier and more simple. This is similar to what is done with reducing fractions.
Factoring will also work with regular equations. So, if two terms have a single factor in common, it is a good idea to factor even. This is the easiest way to solve these types of problems in most cases. Remember that the test makers are consciously trying to trick the test takers so knowing how to get around the trickery is important.
Factoring with Exponents
When factoring with exponents, it is easy to remember the exponent rules. So, when they are set up like a fraction it is a matter of subtracting exponents.
