x in (-oo:+oo)
X+((x^1)/2)*x+(1/2)*x = 360 // - 360
X+((x^1)/2)*x+(1/2)*x-360 = 0
X+(x/2)*x+(1/2)*x-360 = 0
X+1/2*x^2+1/2*x-360 = 0
DELTA = (1/2)^2-(1/2*4*(X-360))
DELTA = 1/4-2*(X-360)
1/4-2*(X-360) = 0
(-2*4*(X-360))/4+1/4 = 0
1-2*4*(X-360) = 0
2881-8*X = 0
(2881-8*X)/4 = 0
(2881-8*X)/4 = 0 // * 4
2881-8*X = 0
2881-8*X = 0 // - 2881
-8*X = -2881 // : -8
X = -2881/(-8)
X = 2881/8
DELTA = 0 <=> t_1 = 2881/8
x = -1/2/(1/2*2) i X = 2881/8
x = -1/2 i X = 2881/8
( x = ((1/4-2*(X-360))^(1/2)-1/2)/(1/2*2) or x = (-(1/4-2*(X-360))^(1/2)-1/2)/(1/2*2) ) i X > 2881/8
( x = (1/4-2*(X-360))^(1/2)-1/2 or x = -((1/4-2*(X-360))^(1/2)+1/2) ) i X > 2881/8
X-2881/8 > 0
X-2881/8 > 0 // + 2881/8
X > 2881/8
