Solution of the D.E y’’ + 3y’ + 2y = 12x2 when solved using the method of undetermined coefficients is ________

y = c1 ex + c2 e2x + 2 – 11x + x2

y = c1 e – x + c2 e – 2x + 18 + 21x + 3x2

y = c1 ex + c2 e – 2x + 11 + 18x + 2x2

y = c1 e – x + c2 e – 2x + 21 – 18x + 6x2

Solution of the D.E y’’ + 3y’ + 2y = 12x2 when solved using the
