Solution for (30/x)-(30/2x)=3 equation:


D( x )

x = 0

x = 0

x = 0

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

30/x-((30/2)*x) = 3 // - 3

30/x-((30/2)*x)-3 = 0

30/x-15*x-3 = 0

30*x^-1-15*x^1-3*x^0 = 0

(30*x^0-15*x^2-3*x^1)/(x^1) = 0 // * x^2

x^1*(30*x^0-15*x^2-3*x^1) = 0

x^1

30-15*x^2-3*x = 0

30-15*x^2-3*x = 0

DELTA = (-3)^2-(-15*4*30)

DELTA = 1809

DELTA > 0

x = (1809^(1/2)+3)/(-15*2) or x = (3-1809^(1/2))/(-15*2)

x = (3*201^(1/2)+3)/(-30) or x = (3-3*201^(1/2))/(-30)

x in { (3*201^(1/2)+3)/(-30), (3-3*201^(1/2))/(-30)}

x in { (3*201^(1/2)+3)/(-30), (3-3*201^(1/2))/(-30) }
