Solution for 15/y^2-11=0 equation: 


D( y )

y^2 = 0

y^2 = 0

y^2 = 0

1*y^2 = 0 // : 1

y^2 = 0

y = 0

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

15/(y^2)-11 = 0

15*y^-2 = 11 // : 15

y^-2 = 11/15

-2 < 0

1/(y^2) = 11/15 // * y^2

1 = 11/15*y^2 // : 11/15

15/11 = y^2

y^2 = 15/11 // ^ 1/2

abs(y) = (15/11)^(1/2)

y = (15/11)^(1/2) or y = -(15/11)^(1/2)

y in { (15/11)^(1/2), -(15/11)^(1/2) }
