(a+2b)5=(2b)5+5(2b)4a+10(2b)3a2+10(2b)2a3+5(2b)a4+a5

 

I have done this with a binomial expansion.  You can simplify it yourself   

If you have questions then ask away

Thanks Radix, I like this   

 

Radix has taken me to a page where students can practice finding the gradient of the line joining 2 points.

This would be a really good practice page for anyone studying linear equations.

I will certainly subject my private students to this.

Thanks Radix
