Hi,

suppose I have the following equation:
\(\frac{a*b+a*R}{b+R}\)

I threw this in maple and on wolfram alpha and Matlab just to see what they do with it to simplify and all came back with: a

Would someone be able to explain how to go about achieving this?

thanks in advance

Don't fret. We all occasionally sit staring at something for a long time only to see (or have pointed out to us) the most simple, obvious solution. It seems like you often spot the solution yourself only after asking someone else -- and I suspect that is not coincidence. The act of explaining the problem to someone else forces you to view the problem somewhat anew.
