Solution for 1/2x^2-1/16x-15/8=0 equation: 


x in (-oo:+oo)

(1/2)*x^2-((1/16)*x)-(15/8) = 0

(1/2)*x^2+(-1/16)*x-15/8 = 0

1/2*x^2-1/16*x-15/8 = 0

DELTA = (-1/16)^2-(-15/8*1/2*4)

DELTA = 961/256

DELTA > 0

x = ((961/256)^(1/2)+1/16)/(1/2*2) or x = (1/16-(961/256)^(1/2))/(1/2*2)

x = 2 or x = -15/8

x in { -15/8, 2 }
