Exercise algebra.manipulation.rational.simplify
Description
simplify a rational expression (with a variable in a divisor)
Derivation
(x+3)/(x-1)+(x+2)/(x-4)
⇒ algebra.equations.rational.rational-scale(x-4)*(x+3)/((x-1)*(x-4))+(x-1)*(x+2)/((x-1)*(x-4))
⇒ algebra.equations.rational.rational-plus((x-4)*(x+3)+(x-1)*(x+2))/((x-1)*(x-4))
⇒ algebra.equations.linear.distr-times(x^2-x-12+x^2+x-2)/((x-1)*(x-4))
⇒ algebra.equations.linear.merge(2*x^2-14)/((x-1)*(x-4))
