Exercise algebra.manipulation.rational.simplify
Description
simplify a rational expression (with a variable in a divisor)
Derivation
(x^2+5*x+6)/(x^3-x^2-6*x)
⇒ algebra.equations.polynomial.factor-varpower(x^2+5*x+6)/(x*(x^2-x-6))
⇒ algebra.equations.quadratic.nice-factors(x^2+5*x+6)/(x*(x+2)*(x-3))
⇒ algebra.equations.quadratic.nice-factors(x+2)*(x+3)/(x*(x+2)*(x-3))
⇒ algebra.equations.rational.cancel-div, clipboard=[condition == (x /= -2)](x+3)/(x*(x-3))
