I am acquainted with differentiating equations like (2x+5)^2 ( by chain rule and the direct method). But how do i go about with the equation 12/(x^2+3)? The specific doubt is that the answer given -12(x^2+3)^-2 into(multiplied by) 2x. Im getting the answer, but its not multiplied by 2x, so i get -12(x^2+3)^-2. I dont know why
