Consecutive Integers and Their Products

The video tutorial explains how to find pairs of consecutive integers whose product is 110. It begins by setting up the equation x(x+1)=110, then solves the quadratic equation by factoring. The solutions are verified to ensure they are correct, resulting in the integer pairs (10, 11) and (-11, -10).

What is the product of two consecutive integers that we are trying to find?

• 100

• 110
