Solution for -x-1=2/3x^2-3x-1 equation: 


x in (-oo:+oo)

-x-1 = (2/3)*x^2-(3*x)-1 // - (2/3)*x^2-(3*x)-1

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

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

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

DELTA = 2^2-(-2/3*0*4)

DELTA = 4

DELTA > 0

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

x = 0 or x = 3

x in { 0, 3 }
