Exercise algebra.manipulation.rational.simplify

Description
simplify a rational expression (with a variable in a divisor)

Derivation

(x^2+3*x-4)/(x*(x^2-6*x+5))

⇒ algebra.equations.quadratic.nice-factors

(x^2+3*x-4)/(x*(x-1)*(x-5))

⇒ algebra.equations.quadratic.nice-factors

(x-1)*(x+4)/(x*(x-1)*(x-5))

⇒ algebra.equations.rational.cancel-div, clipboard=[condition == (x /= 1)]

(x+4)/(x*(x-5))
