Solution for 1/5y2=-y-1/10 equation: 


y in (-oo:+oo)

(1/5)*y^2 = -y-(1/10) // + -y-(1/10)

(1/5)*y^2+y+1/10 = 0

1/5*y^2+y+1/10 = 0

DELTA = 1^2-(1/10*1/5*4)

DELTA = 23/25

DELTA > 0

y = ((23/25)^(1/2)-1)/(1/5*2) or y = (-(23/25)^(1/2)-1)/(1/5*2)

y = 5/2*((23/25)^(1/2)-1) or y = -5/2*((23/25)^(1/2)+1)

y in { -5/2*((23/25)^(1/2)+1), 5/2*((23/25)^(1/2)-1) }
