Accepted Answer

Option 1: $y\left(\frac{dy}{dx}\right)^2+2x\left(\frac{dy}{dx}\right)-y=0$

Answer

$y\left(\frac{dy}{dx}\right)^2+2x\left(\frac{dy}{dx}\right)-y=0$

Answer

$y\left(\frac{dy}{dx}\right)+2x\left(\frac{dy}{dx}\right)-y=0$

Answer

$y\left(\frac{dy}{dx}\right)^2-2x\left(\frac{dy}{dx}\right)+y=0$

Answer

$y\left(\frac{dy}{dx}\right)^2-2x\left(\frac{dy}{dx}\right)-y=0$
