Solution for 3x/16-x^2/4/4-x equation: 


x in (-oo:+oo)

(3*x)/16-(((x^2)/4)/4)-x = 0

(-1/16)*x^2+(3*x)/16-x = 0

-1/16*x^2-13/16*x = 0

DELTA = (-13/16)^2-(-1/16*0*4)

DELTA = 169/256

DELTA > 0

x = ((169/256)^(1/2)+13/16)/(-1/16*2) or x = (13/16-(169/256)^(1/2))/(-1/16*2)

x = -13 or x = 0

x in { -13, 0 }
