For this case we have the following quadratic functions:
Revenue:
Cost:
Then, we observe that the profit is given by the following mathematical relationship:
Substituting values we have:
Making the corresponding calculations we have:
Answer:
An expression that represents the profit is:
Our answer is 
Our greatest common factor, or GCF, is
, so when we factor is out, our divide each term by , we get our answer. To check this, we can multiply the back across the parenthesis and see if we get the same result as our initial question.
