## 1 + [(s+2)/s] + [4/s(s-1)] = 4s(s+20/s^2 + 1

In a previous thread I was shown the solution to a similar problem - using the rule of a/m + b/n = (an + bm)/mn. To my knowledge this is only applicable when there are two fractions.

I would like to see the simplification process of this.

Can anyone help?

Regards.

Don't know where you dug up this equation, but fyi, it works out to a rather nasty quartic equation that requires technology to solve (two irrational real roots). If you are trying to learn the nuances of algebra. I recommend you pick an equation that's a bit easier to work.

My apologies folks - I misread the equation. I have a denominator in an equation that is 1 + s+2/s + 4/s(s-1). I would like to see this simplified. I have done this stuff to the death in a past life - it has been a while that's all and I'm still cleaning off the rust :-)

Sorry to trouble you all, and thanks so far.

Regards.
