Differential equations — practice question

For a general point on the curve, the coordinates $(x, y)$ satisfy the differential equation $x\frac{dy}{dx} = (1 - 2x^2)y$, for $x > 0$. It is also given that $y = 1$ when $x = 1$.
(main)[6]

Solve the differential equation, giving an expression for $y$ in terms of $x$.
