The general solution of the differential equation xdy/dx+2y = x^2, x≠…

The correct answer is Option (1) → $y=\frac{x^2}{4}+\frac{c}{x^2}$(c is constant of integration)

$x\frac{dy}{dx}+2y = x^2$

$\frac{1}{x}(x\frac{dy}{dx}+2y)=\frac{1}{x}(x^2)⇒\frac{dy}{dx}+\frac{2}{x}y=x$

so $I.F.=e^{\frac{2}{x}}dx=e^{2\log|x|}=x^2$

so multiplying eq. with $x^2$ and integrating

$⇒∫x^2\frac{dy}{dx}+2xydx=∫x^3dx$

$⇒x^2y=\frac{x^4}{4}+C⇒y=\frac{x^2}{4}+\frac{C}{x^2}$
