Exercise calculus.differentiation.quotient
Description
Use the quotient-rule to find the derivative of a polynomial. Only remove parentheses in the numerator.
Derivation
((x+4)*D(x) (-3)+3*D(x) (x+4))/(x+4)^2
⇒ calculus.differentiation.deriv-of-poly3*D(x) (x+4)/(x+4)^2
⇒ calculus.differentiation.deriv-of-poly3/(x+4)^2
