Solution for 9y^2-1/2y-1*1-2y/3y-1 equation: 


y in (-oo:+oo)

9*y^2-(((2*y)/3)*y)-((1/2)*y)-(1*1)-1 = 0

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

25/3*y^2-1/2*y-2 = 0

DELTA = (-1/2)^2-(-2*4*25/3)

DELTA = 803/12

DELTA > 0

y = ((803/12)^(1/2)+1/2)/(2*25/3) or y = (1/2-(803/12)^(1/2))/(2*25/3)

y = 3/50*((803/12)^(1/2)+1/2) or y = 3/50*(1/2-(803/12)^(1/2))

y in { 3/50*(1/2-(803/12)^(1/2)), 3/50*((803/12)^(1/2)+1/2) }
