Solution for 3/4x^2-1/3x-1=0 equation: 


x in (-oo:+oo)

(3/4)*x^2-((1/3)*x)-1 = 0

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

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

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

DELTA = 28/9

DELTA > 0

x = ((28/9)^(1/2)+1/3)/(3/4*2) or x = (1/3-(28/9)^(1/2))/(3/4*2)

x = 2/3*((28/9)^(1/2)+1/3) or x = 2/3*(1/3-(28/9)^(1/2))

x in { 2/3*(1/3-(28/9)^(1/2)), 2/3*((28/9)^(1/2)+1/3) }
