Solve `(x^(2)-y^(2))(dy)/(dx)=2xy`

Solve: (x^(2)+y^(2))(dy)/(dx)=xy

The differential equations of all circle touching the x-axis at orgin is (a) (y^(2)-x^(2))=2xy((dy)/(dx)) (b) (x^(2)-y^(2))(dy)/(dx)=2xy ( c ) (x^(2)-y^(2))=2xy((dy)/(dx)) (d) None of these

Solve: (x+y)^(2)(dy)/(dx)=a^(2)

Solve (x+y)^(2)(dy)/(dx)=a^(2)

Solve: (x^2+2xy+y^2+1)(dy)/(dx)=2(x+y)

Solve (1+x^(2))(dy)/(dx)=xy

Solve -x^(2)(dy)/(dx)=2xy+y^(2)

y^(2)+x^(2)(dy)/(dx)=xy(dy)/(dx)

x^(2)(dy)/(dx)+y^(2)=xy

Solve: (x-y)^2(dy)/(dx)=a^2
