Solve the given differential equation. (The form of yp is given.)D2y - 2Dy + y = x2 + 2x + sin 2x(Let yp = Ax2 + Bx + C + E sin 2x + F cos 2x.)
A. y = c1ex + c2xex + 6x2 + 6x + 10 sin 2x + cos 2x
B. y = c1ex + c2xex + 6x2 + 6x + 10 + sin 2x +
cos 2x
C. y = c1ex + 6x2 + 6x + 10 - sin 2x +
cos 2x
D. y = c1ex + c2xex + 6x2 + 6x + 10 - cos 2x +
sin 2x
