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