(x*D(x) (x-2)+D(x) (x-2)-(x-2)*D(x) (x+1))/(x^2+2*x+1)
⇒ calculus.differentiation.deriv-of-poly(x+D(x) (x-2)-(x-2)*D(x) (x+1))/(x^2+2*x+1)
⇒ calculus.differentiation.deriv-of-poly(x+1-(x-2)*D(x) (x+1))/(x^2+2*x+1)
⇒ calculus.differentiation.deriv-of-poly(x+1-x+2)/(x^2+2*x+1)
⇒ algebra.equations.linear.merge3/(x^2+2*x+1)
