Mengyuan Wang, I think you made a mistake.

The second linear independent solution y2 should be just (x^2e^x)/2. I think it is caused by the additional c. If you do not include the c when calculating y2, your results will be right.

And the coefficients of the general solution are also wrong, c1 should be -1/2, c2 should be 1/2.
