Finding Pairs of Numbers

Mr. Cozy introduces a mini unit on factoring quadratic expressions, focusing on diamond puzzles. He explains the concept of diamond puzzles, where students find two numbers that add up to a given top number and multiply to a bottom number. Several examples are provided to illustrate the process, and students are assigned a worksheet to practice further. The video concludes with a reminder of the assignment to complete the even-numbered problems.
