Solution for 2x+1/2-4x/2x-1=-1 equation: 


x in (-oo:+oo)

2*x-(((4*x)/2)*x)+1/2-1 = -1 // + 1

2*x-(((4*x)/2)*x)+1/2-1+1 = 0

2*x-2*x^2+1/2-1+1 = 0

2*x-2*x^2+1/2 = 0

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

DELTA = 8

DELTA > 0

x = (8^(1/2)-2)/(-2*2) or x = (-8^(1/2)-2)/(-2*2)

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

x in { (2*2^(1/2)-2)/(-4), (-2*2^(1/2)-2)/(-4) }
