Exercise algebra.manipulation.rational.simplify

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

Derivation

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

⇒ algebra.equations.quadratic.nice-factors

(x^2+4*x-5)/((x-1)*(x+6))

⇒ algebra.equations.quadratic.nice-factors

(x-1)*(x+5)/((x-1)*(x+6))

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

(x+5)/(x+6)
