y^{'''}-y^'=3-7t

y^{^{'''}} - y^{^{'}} = 3 - 7 t

y = c_{1} + c_{2} e^{- t} + c_{3} e^{t} + \frac{7 t ^{2}}{2} - 3 t

Solution steps

y^{'''} (t) - y^{'} (t) = 3 - 7 t

Solve linear ODE:

y = c_{1} + c_{2} e^{- t} + c_{3} e^{t} + \frac{7 t ^{2}}{2} - 3 t

y = c_{1} + c_{2} e^{- t} + c_{3} e^{t} + \frac{7 t ^{2}}{2} - 3 t
