To watch a video of examples of multiplying binomials in two different ways, see the video below. You may not need to watch the entire thing. When I watch the video, some of the writing doesn't show, but I'm not sure if that is just a glitch for me. 

For the next few problems, you'll be multiplying binomials. 

When we multiply these binomials, we get 

To enter the answer, you will enter only the middle and last term (for now, the x-squared won't change). So, for this answer, you would type in 5x, 6

Let's generalize (create a formula) for multiplying two binomials
When multiplied out, the "b" value for this quadratic expression is:

m+n

m-n

mn (m times n)

m/n (m divided by n)
