Which of the following is the general solution of the differential equation dy dx equals the quotient of 4 times x and y?

katovenus [111]

The ODE appears to be

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{4x}y$

It's separable; we can write

$y\,\mathrm dy=4x\,\mathrm dx$

and integrating both sides yields

$\dfrac{y^2}2=2x^2+C$

$\implies y^2=4x^2+C$
