Solution for 2/3z^2-3z-5/3z-3 equation: 


z in (-oo:+oo)

(2/3)*z^2-(3*z)-((5/3)*z)-3 = 0

(2/3)*z^2-3*z+(-5/3)*z-3 = 0

2/3*z^2-14/3*z-3 = 0

DELTA = (-14/3)^2-(-3*2/3*4)

DELTA = 268/9

DELTA > 0

z = ((268/9)^(1/2)+14/3)/(2/3*2) or z = (14/3-(268/9)^(1/2))/(2/3*2)

z = 3/4*((268/9)^(1/2)+14/3) or z = 3/4*(14/3-(268/9)^(1/2))

z in { 3/4*(14/3-(268/9)^(1/2)), 3/4*((268/9)^(1/2)+14/3) }
