Exercise algebra.manipulation.rational.simplify

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

Derivation

3*x/(x-4)+5*x/(x-2)

⇒ algebra.equations.rational.rational-scale

(x-2)*3*x/((x-4)*(x-2))+(x-4)*5*x/((x-4)*(x-2))

⇒ algebra.equations.rational.rational-plus

((x-2)*3*x+(x-4)*5*x)/((x-4)*(x-2))

⇒ algebra.equations.linear.distr-times

(3*x^2-6*x+5*x^2-20*x)/((x-4)*(x-2))

⇒ algebra.equations.linear.merge

(8*x^2-26*x)/((x-4)*(x-2))
