Solution for (1/3)x-(9/18)+(9/12x^2) equation: 


x in (-oo:+oo)

(9/12)*x^2+(1/3)*x-(9/18) = 0

(9/12)*x^2+(1/3)*x-1/2 = 0

3/4*x^2+1/3*x-1/2 = 0

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

DELTA = 29/18

DELTA > 0

x = ((29/18)^(1/2)-1/3)/(3/4*2) or x = (-(29/18)^(1/2)-1/3)/(3/4*2)

x = 2/3*((29/18)^(1/2)-1/3) or x = -2/3*((29/18)^(1/2)+1/3)

x in { -2/3*((29/18)^(1/2)+1/3), 2/3*((29/18)^(1/2)-1/3) }
