Why the dx is being removed from the denominator in every solution?(X^2+1)d(x^3+2)/dx-(x^3+2)d(x^2+1)/dx=(x^2+1)[3x^2+1]-(x^3+2)(2x+0)/[x^2+1]^2

Answer» Why the dx is being removed from the denominator in every solution?

(X^2+1)d(x^3+2)/dx-(x^3+2)d(x^2+1)/dx
=(x^2+1)[3x^2+1]-(x^3+2)(2x+0)/[x^2+1]^2
