Factoring perfect squares: common factor | Mathematics II | High School Math | Khan Academy

Sal factors 16x^3+24x^2+9x as (x)(4x+3)^2.

High School Math on Khan Academy: Did you realize that the word "algebra" comes from Arabic (just like "algorithm" and "al jazeera" and "Aladdin")? And what is so great about algebra anyway? This tutorial doesn't explore algebra so much as it introduces the history and ideas that underpin it.

Dear Khan Academy, I think these would be much easier for kids to understand if they were taught as (A+B)^2, where in this case A = 4x, then the middle term is 2AB which shows that the "x" is part of the A term.

Thank you for the examples. I really like the idea of using different colors for the examples you make. The different colors help me understand so much better. :)
