Exercise algebra.manipulation.rational.simplify

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

Derivation

(a^2-2*a-15)/(a^3-3*a^2-10*a)

⇒ algebra.equations.polynomial.factor-varpower

(a^2-2*a-15)/(a*(a^2-3*a-10))

⇒ algebra.equations.quadratic.nice-factors

(a^2-2*a-15)/(a*(a+2)*(a-5))

⇒ algebra.equations.quadratic.nice-factors

(a+3)*(a-5)/(a*(a+2)*(a-5))

⇒ algebra.equations.rational.cancel-div, clipboard=[condition == (a /= 5)]

(a+3)/(a*(a+2))
