In this problem you will use undetermined coefficients to solve the nonhomogeneous equation
y"- 2y' + y = 2 - t - (6te^t + 6e^t)
initial values y(0)=1 , y'(0)= -1
1) write the form of the particular solution and its derivatives (Use A,B,C for undetermined coeffs)
2)Write General Solution
3)Plug in initial values
