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) (x-3)-(x-3)*D(x) (x+4))/(x+4)^2
⇒ calculus.differentiation.deriv-of-poly(x+4-(x-3)*D(x) (x+4))/(x+4)^2
⇒ calculus.differentiation.deriv-of-poly(x+4-x+3)/(x+4)^2
⇒ algebra.equations.linear.merge7/(x+4)^2
