Hope you not solving for the DE
$y = c_1e^x + c_2xe^x$ ←
$y = c_1e^x + c_2xe^x$ ← eq (1)
$y' = c_1e^x + c_2(xe^x + e^x)$ ← eq (2)
$y'' = c_1e^x + c_2(xe^x + 2e^x)$ ← eq (3)
eq (2) - eq (1)
$y' - y = c_2e^x$ ← eq (4)
eq (3) - eq (2)
$y'' - y' = c_2e^x$ ← eq (5)
eq (5) - eq (4)
$(y'' - y') - (y' - y) = 0$
$y'' - 2y' + y = 0$ answer
