In this problem you will use variation of parameters to solve the nonhomogeneous equation y″+5y′+6y=−e^(−2t)
A. Write the characteristic equation for the associated homogeneous equation. (Use r for your variable.)
B. Write the fundamental solutions for the associated homogeneous equation and their Wronskian.
C. Write the general solution. (Use c1 and c2 for c1c1 and c2c2).
