$$\\(a+2b)^5=(2b)^5+5*(2b)^4*a+10*(2b)^3*a^2+10*(2b)^2*a^3+5*(2b)*a^4+a^5\\\\$$

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

If you have questions then ask away  

Good morning Melody ,

thank you for your answer! Here you see  " Pascal's Triangle".

Thanks Radix    

Hi Melody,

please have a look for  " Jeder Schuss (shoot) ein Treffer " in the German Forum.

Gruß radix !

Can you cut and paste the address please Radix so that I can go straight to it ?

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
