1. Subtract

Since we are subtracting fractions, we need to find common denominators. First factor both denominators.

Fill in the missing factors.

Now that we have common denominators, we need only subtract the numerators. Subtracting polynomials amounts to removing parentheses and combining like terms.

At this point, always check to see if the fraction can be reduced. In this case, there is a factor of   2   in both of the terms on top.

We find that there is a factor of   2x + 3   in both the top and bottom that we can cancel out leaving us with
