Solution of (x+y)^2 \frac{dy}{dx} = a^2 ('a' being a constant) is

Correct Answer is : (x+y)a=tany+ca, c is an arbitrary constant

\frac{(x+y)}{a} = \tan \frac{y+c}{a}, c is an arbitrary constant

xy = a tan cx, c is an arbitrary constant

x/{a} = \tan y/{c}, c is an arbitrary constant

xy = tan(x + c), c is an arbitrary constant
