Show that the function y = ax^m + bx^-m is the solution of the differential equation x^2y\"+xy\'-m^2y = 0
Solution
y\'\' = (y\')\'
y\' = amxm-1-mbx-m-1
y\'\' = am(m-1)xm-2+m(m+1)bx-m-2
x2y\'\' = x2* am(m-1)xm-2+m(m+1)bx-m-2
xy\' = x(amxm-1-mbx-m-1)
-m2*y =-axmm2 - m2bx-m
Adding all these we get: 0.
So, The equation y=axm+bx-m satisfies the differential equation.
