About This Lesson
Video by Julie Harland http://yourmathgal.com This video was created because Barry, an 8th grade Algebra I student, watched my video titled Factoring 14b, and wrote to ask me why the method of factoring shown in Factoring 14b works. So here is the explanation. Thanks to Barry for being curious and asking! That's terrific!<br />For more great math videos visit: www.youtube.com/user/videosbyjulieharland/videos<br />Aligned to Common Core State Standard: HSA-SSE.3
An interesting extension for students to prove why the box method of factoring works.
