Given the differential equation (2x+y)dx+(x+3y2)dy=0(2x + y)dx + (x + 3y^2)dy = 0(2x+y)dx+(x+3y2)dy=0, which of the following is true?
It is a separable equation.
It is an exact equation because ∂M∂y=∂N∂x\frac{\partial M}{\partial y} = \frac{\partial N}{\partial x}∂y∂M=∂x∂N.
It is a Bernoulli equation.
The equation has no solution.
