Reducing Rational Expressions

We must always reduce rational expressions when we can to make the expression simple. In order to do this we must find the excluded values for X.  The restrictions on the variables is when the value makes the denominator zero. Then we should see if we are able to factor the numerator and the demoniator. Next, cancel any factors that are possible. Finally simplify the expression. Keep in mind that factors are constants/variables that are mulitplied or divided together.  Terms on the other hand, are constants/variables that are added or subtracted.
