t in (-oo:+oo)
-260 = 6*t-((5/2)*t^2) // - 6*t-((5/2)*t^2)
(5/2)*t^2-(6*t)-260 = 0
(5/2)*t^2-6*t-260 = 0
5/2*t^2-6*t-260 = 0
DELTA = (-6)^2-(-260*5/2*4)
DELTA = 2636
DELTA > 0
t = (2636^(1/2)+6)/(2*5/2) or t = (6-2636^(1/2))/(2*5/2)
t = (2*659^(1/2)+6)/5 or t = (6-2*659^(1/2))/5
t in { (6-2*659^(1/2))/5, (2*659^(1/2)+6)/5 }
