Solution for y^(-2)=25/4 equation: 


D( y )

y = 0

y = 0

y = 0

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

y^-2 = 25/4 // - 25/4

y^-2-(25/4) = 0

y^-2-25/4 = 0

1*y^-2 = 25/4 // : 1

y^-2 = 25/4

-2 < 0

1/(y^2) = 25/4 // * y^2

1 = 25/4*y^2 // : 25/4

4/25 = y^2

y^2 = 4/25 // ^ 1/2

abs(y) = 2/5

y = 2/5 or y = -2/5

y in { 2/5, -2/5 }
