"a single algebraic fraction"
Hi Benjamin;
(-6s2)-(7s/9s)+(3/s)
(-6s2)-(7/9)+(3/s)
The concept of positive indices means that the exponentials are positive.
The only negative exponential would be 3s-1.  It is already represented as 3/s.  There is nothing to correct.  However, simplification of (7s/9s) is required.
