Solution for 3x-13=10/x equation: 


D( x )

x = 0

x = 0

x = 0

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

3*x-13 = 10/x // - 10/x

3*x-(10/x)-13 = 0

3*x-10*x^-1-13 = 0

3*x^1-10*x^-1-13*x^0 = 0

(3*x^2-13*x^1-10*x^0)/(x^1) = 0 // * x^2

x^1*(3*x^2-13*x^1-10*x^0) = 0

x^1

3*x^2-13*x-10 = 0

3*x^2-13*x-10 = 0

DELTA = (-13)^2-(-10*3*4)

DELTA = 289

DELTA > 0

x = (289^(1/2)+13)/(2*3) or x = (13-289^(1/2))/(2*3)

x = 5 or x = -2/3

x in { -2/3, 5} 

x in { -2/3, 5 }
