Solution for y^-2=36/25 equation: 


D( y )

y = 0

y = 0

y = 0

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

y^-2 = 36/25 // - 36/25

y^-2-(36/25) = 0

y^-2-36/25 = 0

1*y^-2 = 36/25 // : 1

y^-2 = 36/25

-2 < 0

1/(y^2) = 36/25 // * y^2

1 = 36/25*y^2 // : 36/25

25/36 = y^2

y^2 = 25/36 // ^ 1/2

abs(y) = 5/6

y = 5/6 or y = -5/6

y in { 5/6, -5/6 }
