Exercise algebra.manipulation.rational.simplify

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

Derivation

(2*p^2+8*p)/(p^2-16)

⇒ algebra.equations.quadratic.nice-factors

(2*p^2+8*p)/((p+4)*(p-4))

⇒ algebra.equations.quadratic.common-factor

2*p*(p+4)/((p+4)*(p-4))

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

2*p/(p-4)
