Exercise calculus.differentiation.quotient
Description
Use the quotient-rule to find the derivative of a polynomial. Only remove parentheses in the numerator.
Derivation
((2*x-1)*D(x) 3-3*D(x) (2*x-1))/(2*x-1)^2
⇒ calculus.differentiation.deriv-of-poly-3*D(x) (2*x-1)/(2*x-1)^2
⇒ calculus.differentiation.deriv-of-poly-6/(2*x-1)^2
