Exercise algebra.manipulation.rational.simplify

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

Derivation

(a^2-9)/(a^3-4*a^2+3*a)

⇒ algebra.equations.polynomial.factor-varpower

(a^2-9)/(a*(a^2-4*a+3))

⇒ algebra.equations.quadratic.nice-factors

(a^2-9)/(a*(a-1)*(a-3))

⇒ algebra.equations.quadratic.nice-factors

(a+3)*(a-3)/(a*(a-1)*(a-3))

⇒ algebra.equations.rational.cancel-div, clipboard=[condition == (a /= 3)]

(a+3)/(a*(a-1))
