Solution for 2x/4.5=22.5/x equation: 


D( x )

x = 0

x = 0

x = 0

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

(2*x)/4.5 = 22.5/x // - 22.5/x

(2*x)/4.5-(22.5/x) = 0

(2*x)/4.5-22.5*x^-1 = 0

0.44444444*x-22.5*x^-1 = 0

x^-1*(0.44444444*x^2-22.5) = 0

0.44444444*x^2 = 22.5 // : 0.44444444

x^2 = 50.62500051

x^2 = 50.62500051 // ^ 1/2

abs(x) = 50.62500051^(1/2)

x = 50.62500051^(1/2) or x = -50.62500051^(1/2)

1/x = 0

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

x^-1 = 0

x należy do O

x in { 50.62500051^(1/2), -50.62500051^(1/2) }
