The third method is the Box Method. This method works for every problem! Here’s how you do it. Multiply (3x – 5)(5x + 2) Draw a box. Write a polynomial.

Simplify by combining like terms: 1. (5x 3 – 3x) + (8x 3 + 4x) = 2. (4y 3 + 8xy) – (3xy + 9y 3 )= 3. (5x 3 – 2y 3 ) – (5y 3 + 6x 3 )= 13x 3 + x -5y 3 +

More FOIL

We can’t call this FOIL but it is the same idea! Combine Like Terms

Try These (9d – 4)(9d + 4) Answer: 81d2 – 16 (10g + 13h2)(10g – 13h2) Answer: 100g2 – 169h4 What do you notice about these two problems? Why is the middle term gone? This could be a “short cut” for future problems.
