Description
Use the quotient-rule to find the derivative of a polynomial. Only remove parentheses in the numerator.

Derivation

Final term is not finished

((x-1)*(D(x) x+D(x) 5)-x*D(x) (x-1)-5*D(x) (x-1))/(x-1)^2

⇒ calculus.differentiation.deriv-of-poly

((x-1)*(1+D(x) 5)-x*D(x) (x-1)-5*D(x) (x-1))/(x-1)^2

⇒ calculus.differentiation.deriv-of-poly

(x-1-x*D(x) (x-1)-5*D(x) (x-1))/(x-1)^2
