Exercise algebra.manipulation.rational.simplify

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

Derivation

(x^2+2*x-8)/(x^2+10*x+24)

⇒ algebra.equations.quadratic.nice-factors

(x^2+2*x-8)/((x+4)*(x+6))

⇒ algebra.equations.quadratic.nice-factors

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

⇒ algebra.equations.rational.cancel-div, clipboard=[condition == (x /= -4)]

(x-2)/(x+6)
