Second order DE, reduction of order method?

Click For Summary
SUMMARY

The discussion focuses on solving the second-order differential equation \(x^2y'' - xy' - 3y = 0\) using the reduction of order method. The provided solutions are \(y_1 = \frac{1}{x}\) and \(y_2 = x^3\). The general solution is confirmed as \(y = c_1 \left(\frac{1}{x}\right) + c_2 (x^3)\), which is derived through the superposition of homogeneous equations. The participants validate the simplicity of the solution, indicating confidence in the method applied.

Homework Statement



find general solution of x2y''-xy'-3y=0

Homework Equations



two solutions are given, y1=1/x and y2=x3

The Attempt at a Solution



i think this is a reduction of order question? the only theory i can find in my text for second order DE relates to constant coefficients, and obvioulsy these ones arent. anyone have some method for reduction of order? or am i going about this the wrong way?

thanks

hold up... by superposition of homogeneous equations...

with y1 and y2 solutions, then a general solution would just be y=c1(1/x)+c2(x^3) ??

but that seems too easy...
