Solution for 2-5/6x-1/8x^2 equation: 


x in (-oo:+oo)

2-((1/8)*x^2)-((5/6)*x) = 0

(-1/8)*x^2+(-5/6)*x+2 = 0

2-1/8*x^2-5/6*x = 0

DELTA = (-5/6)^2-(-1/8*2*4)

DELTA = 61/36

DELTA > 0

x = ((61/36)^(1/2)+5/6)/(-1/8*2) or x = (5/6-(61/36)^(1/2))/(-1/8*2)

x = -4*((61/36)^(1/2)+5/6) or x = -4*(5/6-(61/36)^(1/2))

x in { -4*((61/36)^(1/2)+5/6), -4*(5/6-(61/36)^(1/2)) }
