In this lesson, we learn how to find two numbers whose difference is 6 and whose product is as small as possible. We explore different possibilities and then solve the problem algebraically by using a quadratic equation and the vertex point. The smallest product is found to be -9, which corresponds to the numbers 3 and -3, whose difference is indeed 6. This lesson provides a great way to practice problem-solving skills and algebraic techniques in a fun and engaging way.
We do this problem: Find 2 numbers whose difference is 6 and whose product is as small as possible. This is done using a quadratic equation and the vertex point.
