How do you find 2 numbers whose difference is 6 and whose product is as small as possible?
How do you find the 2 numbers that minimize their product and have a given sum or difference?

This lesson is another example of using a parabola to find a minimum or maximum in a word problem. In this case, the goal is to minimize the product of two numbers when their difference is 6. An equation is set up and the vertex is found in order to solve this problem. All steps involved are explained.
