#12 Rational expressions don't simply correctly

Qalculate doesn't factor a (-1) out of a function to check to see if it can simplify further. Example: 2x/(x-5) + 5/(5-x) simplifies to ((x − 5)(2x − 5)) ∕ (5 − x)^2 when it could be further simplified to (5 - 2x)/(5 - x) by factoring a (-1) out of the denominator and canceling with the (x - 5) in the numerator. Maybe there is a feature to enable this automatically, but I think simplifying technique should be on by default.

  • I am moving this to the "feature request" tracker. As developers, we need to decide how much computer algebra capabilities qalculate should have (if any).
