What is the characteristic equation of an=6an−1−11an−2+6an−3a_n = 6a_{n-1} - 11a_{n-2} + 6a_{n-3}an=6an−1−11an−2+6an−3?
r3−6r2+11r−6=0r^3 - 6r^2 + 11r - 6 = 0r3−6r2+11r−6=0
r3+6r2+11r+6=0r^3 + 6r^2 + 11r + 6 = 0r3+6r2+11r+6=0
r3−6r2+11r+6=0r^3 - 6r^2 + 11r + 6 = 0r3−6r2+11r+6=0
r3=6r2−11r−6r^3 = 6r^2 - 11r - 6r3=6r2−11r−6
