x in (-oo:+oo)
6*x^2-(((3*x)/4)*x^2)-((6/8)*x^2)+(8*x)/3+4*x = 0
(-3/4)*x^3+6*x^2+(-3/4)*x^2+(8*x)/3+4*x = 0
21/4*x^2-3/4*x^3+20/3*x = 0
x*(21/4*x-3/4*x^2+20/3) = 0
21/4*x-3/4*x^2+20/3 = 0
DELTA = (21/4)^2-(-3/4*4*20/3)
DELTA = 761/16
DELTA > 0
x = ((761/16)^(1/2)-21/4)/(-3/4*2) or x = (-(761/16)^(1/2)-21/4)/(-3/4*2)
x = -2/3*((761/16)^(1/2)-21/4) or x = 2/3*((761/16)^(1/2)+21/4)
x = 0
x = 0
x in { -2/3*((761/16)^(1/2)-21/4), 2/3*((761/16)^(1/2)+21/4), 0 }
