Find a linear second-order differential equation
F(x, y, y', y") = 0 for which y = c₁x + c₂x² is a two-
parameter family of solutions. Make sure that your equa-
tion is free of the arbitrary parameters c₁ and c₂.
Qualitative information about a solution y = (x) of a
differential equation can often be obtained from the
equation itself. Before working Problems 55–58, recall
the geometric significance of the derivatives dy/dx
and d²y/dx².
