SUMMARY
The general solution to the second order differential equation y'' - 2(y')^2 = 0 can be approached by substituting u = y'. This leads to the first-order equation u' - 2u^2 = 0, which simplifies to u' = 2u^2. The correct method involves expressing u' as du/dx, allowing the use of separation of variables to solve the equation effectively.
