Solution for 6x-4-x^2=x/2 equation: 


x in (-oo:+oo)

6*x-x^2-4 = x/2 // - x/2

6*x-x^2-(x/2)-4 = 0

11/2*x-x^2-4 = 0

DELTA = (11/2)^2-(-4*(-1)*4)

DELTA = 57/4

DELTA > 0

x = ((57/4)^(1/2)-11/2)/(-1*2) or x = (-(57/4)^(1/2)-11/2)/(-1*2)

x = ((57/4)^(1/2)-11/2)/(-2) or x = ((57/4)^(1/2)+11/2)/2

x in { ((57/4)^(1/2)-11/2)/(-2), ((57/4)^(1/2)+11/2)/2 }
