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
