((x-1)*D(x) (x+5)-x*(D(x) x-D(x) 1)-5*D(x) (x-1))/(x-1)^2
⇒ calculus.differentiation.deriv-of-poly((x-1)*D(x) (x+5)-x*(1-D(x) 1)-5*D(x) (x-1))/(x-1)^2
⇒ calculus.differentiation.deriv-of-poly((x-1)*D(x) (x+5)-x-5*D(x) (x-1))/(x-1)^2
⇒ calculus.differentiation.deriv-of-poly(x-1-x-5*D(x) (x-1))/(x-1)^2
⇒ algebra.equations.linear.merge(-1-5*D(x) (x-1))/(x-1)^2
