Solution for x2-2/3x-3 equation: 


x in (-oo:+oo)

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

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

x^2-2/3*x-3 = 0

DELTA = (-2/3)^2-(-3*1*4)

DELTA = 112/9

DELTA > 0

x = ((112/9)^(1/2)+2/3)/(1*2) or x = (2/3-(112/9)^(1/2))/(1*2)

x = ((112/9)^(1/2)+2/3)/2 or x = (2/3-(112/9)^(1/2))/2

x in { (2/3-(112/9)^(1/2))/2, ((112/9)^(1/2)+2/3)/2 }
