Solution for 2x^2-1/2x=1/8 equation: 


x in (-oo:+oo)

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

2*x^2-((1/2)*x)-(1/8) = 0

2*x^2+(-1/2)*x-1/8 = 0

2*x^2-1/2*x-1/8 = 0

DELTA = (-1/2)^2-(-1/8*2*4)

DELTA = 5/4

DELTA > 0

x = ((5/4)^(1/2)+1/2)/(2*2) or x = (1/2-(5/4)^(1/2))/(2*2)

x = ((5/4)^(1/2)+1/2)/4 or x = (1/2-(5/4)^(1/2))/4

x in { (1/2-(5/4)^(1/2))/4, ((5/4)^(1/2)+1/2)/4 }
