Solution for y+3/y=77/56 equation: 


D( y )

y = 0

y = 0

y = 0

y in (-oo:0) U (0:+oo)

y+3/y = 77/56 // - 77/56

y+3/y-(77/56) = 0

y+3/y-11/8 = 0

1*y^1+3*y^-1-11/8*y^0 = 0

(1*y^2-11/8*y^1+3*y^0)/(y^1) = 0 // * y^2

y^1*(1*y^2-11/8*y^1+3*y^0) = 0

y^1

y^2+(-11/8)*y+3 = 0

y^2+(-11/8)*y+3 = 0

DELTA = (-11/8)^2-(1*3*4)

DELTA = -647/64

DELTA < 0

y in { }
