Solution for x^2/12-x/2=15/4 equation: 


x in (-oo:+oo)

(x^2)/12-(x/2) = 15/4 // - 15/4

(x^2)/12-(x/2)-(15/4) = 0

(x^2)/12-(x/2)-15/4 = 0

1/12*x^2-1/2*x-15/4 = 0

DELTA = (-1/2)^2-(-15/4*1/12*4)

DELTA = 3/2

DELTA > 0

x = ((3/2)^(1/2)+1/2)/(1/12*2) or x = (1/2-(3/2)^(1/2))/(1/12*2)

x = 6*((3/2)^(1/2)+1/2) or x = 6*(1/2-(3/2)^(1/2))

x in { 6*(1/2-(3/2)^(1/2)), 6*((3/2)^(1/2)+1/2) }
