hello can someone explain how to guess the yp for this Non-homogeneous differential equation(adsbygoogle = window.adsbygoogle || []).push({});

y'' - 2y' + y = te^t

characteristic polynomial: (y - 1)^2 so the characteristic roots are: y1=y2= 1

c1 and c2 are constant

for yh = (c1)e^t + (c2)te^t

please explained how to guess for te^t
