Solution for x2-5x/x-5=15-2x equation: 


D( x )

x = 0

x = 0

x = 0

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

x^2-((5*x)/x)-5 = 15-(2*x) // - 15-(2*x)

x^2+2*x-((5*x)/x)-15-5 = 0

x^2+2*x-15-5-5 = 0

x^2+2*x-25 = 0

DELTA = 2^2-(-25*1*4)

DELTA = 104

DELTA > 0

x = (104^(1/2)-2)/(1*2) or x = (-104^(1/2)-2)/(1*2)

x = (2*26^(1/2)-2)/2 or x = (-2*26^(1/2)-2)/2

x in { (-2*26^(1/2)-2)/2, (2*26^(1/2)-2)/2 }
