Solution for x+4/3x^2+11x-4 equation: 


x in (-oo:+oo)

(4/3)*x^2+x+11*x-4 = 0

4/3*x^2+12*x-4 = 0

DELTA = 12^2-(-4*4/3*4)

DELTA = 496/3

DELTA > 0

x = ((496/3)^(1/2)-12)/(4/3*2) or x = (-(496/3)^(1/2)-12)/(4/3*2)

x = 3/8*((496/3)^(1/2)-12) or x = -3/8*((496/3)^(1/2)+12)

x in { -3/8*((496/3)^(1/2)+12), 3/8*((496/3)^(1/2)-12) }
