here's my question If $y^2=ax^2+bx+c$ then prove that $y^3[d^2y/dx^2]$ is a constant . I have solved this using the conventional method, taking square root, differentiating w.r.t to x and using chain and quotient rule But can't think of some alternative smaller and more efficient method ?? Can you ?
Also can someone suggest me any alternative to quotient rule I need something more non conventional, time saving and vastly Applicable method .🙂
