Binomial Multiplied by a Trinomial  Visualizing Algebra

0:00  0:04In the case of multiplying a binomial by a trinomial, we just want to add some

0:04  0:08rectangles so we can complete our multiplication. Just like with these numbers,

0:08  0:12I'm going to set up a rectangle, and then I'm going to label each factor along

0:12  0:16the side of the rectangle. This one will be x plus 3, and this one will be x

0:16  0:20squared plus 2x plus 3. Using what you know about multiplication, I want you to

0:20  0:24figure out the area of each of these rectangles. What would they be?
