**Q1** Write the following third order ODE as a system of three first order equations

\[ x^3 \frac{d^3 y}{dx^3} + x^2 \frac{d^2 y}{dx^2} - 2x \frac{dy}{dx} + 2y = 2x^4. \]

*Hint: Start by rewriting the equation in the form of \( y''' = F(x, y, y', y'') \).*

**Q2** State one advantage and one disadvantage of implicit methods for solving ODEs.
