This video tutorial teaches how to multiply polynomials using the FOIL method, a mnemonic for multiplying the First, Outer, Inner, and Last terms. It provides three examples: simplifying (3x - 5)(2x + 7), (x - 7)(5x + 6), and expanding (6r + 8)^2. Each example is broken down step-by-step, demonstrating the multiplication and combination of like terms to reach the final simplified expression.

What does FOIL stand for in polynomial multiplication?

• First, Outer, Inner, Last

• First, Open, Inner, Loop

• First, Outer, Inner, Linear

• Final, Outer, Inner, Last
