Solution for 4/x=x/12.25 equation: 


D( x )

x = 0

x = 0

x = 0

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

4/x = x/12.25 // - x/12.25

4/x-(x/12.25) = 0

4/x-0.08163265*x = 0

4*x^-1-0.08163265*x = 0

x^-1*(4-0.08163265*x^2) = 0

-0.08163265*x^2 = -4 // : -0.08163265

x^2 = 49.00000184

x^2 = 49.00000184 // ^ 1/2

abs(x) = 49.00000184^(1/2)

x = 49.00000184^(1/2) or x = -49.00000184^(1/2)

1/x = 0

1*x^-1 = 0 // : 1

x^-1 = 0

x należy do O

x in { 49.00000184^(1/2), -49.00000184^(1/2) }
