Exercise algebra.manipulation.rational.simplify
Description
simplify a rational expression (with a variable in a divisor)
Derivation
(x-4)/(x+5)+(x-2)/(x-3)
⇒ algebra.equations.rational.rational-scale(x-3)*(x-4)/((x+5)*(x-3))+(x+5)*(x-2)/((x+5)*(x-3))
⇒ algebra.equations.rational.rational-plus((x-3)*(x-4)+(x+5)*(x-2))/((x+5)*(x-3))
⇒ algebra.equations.linear.distr-times(x^2-7*x+12+x^2+3*x-10)/((x+5)*(x-3))
⇒ algebra.equations.linear.merge(2*x^2-4*x+2)/((x+5)*(x-3))
