Solution for 17/d2-9 equation: 


D( d )

d^2 = 0

d^2 = 0

d^2 = 0

1*d^2 = 0 // : 1

d^2 = 0

d = 0

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

17/(d^2)-9 = 0

17*d^-2 = 9 // : 17

d^-2 = 9/17

-2 < 0

1/(d^2) = 9/17 // * d^2

1 = 9/17*d^2 // : 9/17

17/9 = d^2

d^2 = 17/9 // ^ 1/2

abs(d) = (17/9)^(1/2)

d = (17/9)^(1/2) or d = -(17/9)^(1/2)

d in { (17/9)^(1/2), -(17/9)^(1/2) }
