I guess you want to find the Particular Solution of the equation {tex}x(x^2-1) {dx \over dy} = 1 \ at\ y =0, x=2{/tex} 

{tex}It \ can \ be\ written \ as => x(x^2-1) dx = dy{/tex}

=> {tex}(x^3-x) dx =dy{/tex}

On Integrating both side

{tex}{x^4 \over 4 }- {x^2 \over 2} = y{/tex} + c  ....................1

Put x=2 & y=0 in equation 1

c = 2

 Now put value of c in 1

{tex}{x^4 \over 4 }- {x^2 \over 2} = y + 2{/tex}

 

This is the Particular Solution of given differential equation.

Equation 1 is the General Solution of given differential equation.
