Solution for (t^2)/2+2t=1/4 equation: 


t in (-oo:+oo)

(t^2)/2+2*t = 1/4 // - 1/4

(t^2)/2+2*t-(1/4) = 0

(t^2)/2+2*t-1/4 = 0

1/2*t^2+2*t-1/4 = 0

DELTA = 2^2-(-1/4*1/2*4)

DELTA = 9/2

DELTA > 0

t = ((9/2)^(1/2)-2)/(1/2*2) or t = (-(9/2)^(1/2)-2)/(1/2*2)

t = (9/2)^(1/2)-2 or t = -((9/2)^(1/2)+2)

t in { -((9/2)^(1/2)+2), (9/2)^(1/2)-2 }
