use the quadratic formula
(-(b^2) +/-sqrt(b^2 - 4*a*c))/a^2
where
a = the coefficient of the second degree term
b = the coefficient of the first degree term
c = the coefficient of the zero degree term
(-(-6^2) +/-sqrt((-6)^2 - 4*(2)*(-55)))/(2)^2
(-36 +/- sqrt(476))/4
answers: (-18+sqrt(119))/2,(-18-sqrt(119))/2

x = [6 ± â(36 + 440)] / 4
x = [6 ± â(476)] / 4
x = [6 ± (21.8)] / 4
x = 6.95 , x = - 3.95
