Solution for 49-9/C^2=0 equation: 


D( C )

C^2 = 0

C^2 = 0

C^2 = 0

1*C^2 = 0 // : 1

C^2 = 0

C = 0

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

49-(9/(C^2)) = 0

49-9*C^-2 = 0

-9*C^-2 = -49 // : -9

C^-2 = 49/9

-2 < 0

1/(C^2) = 49/9 // * C^2

1 = 49/9*C^2 // : 49/9

9/49 = C^2

C^2 = 9/49 // ^ 1/2

abs(C) = 3/7

C = 3/7 or C = -3/7

C in { 3/7, -3/7 }
