x = 0
x in (-oo:0) U (0:+oo)
x+5/x-(5/1)-7 = 0
x+5/x-7-5 = 0
1*x^1+5*x^-1-12*x^0 = 0
(1*x^2-12*x^1+5*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2-12*x^1+5*x^0) = 0
x^1
x^2-12*x+5 = 0
x^2-12*x+5 = 0
DELTA = (-12)^2-(1*4*5)
DELTA = 124
DELTA > 0
x = (124^(1/2)+12)/(1*2) or x = (12-124^(1/2))/(1*2)
x = (2*31^(1/2)+12)/2 or x = (12-2*31^(1/2))/2
x in { (12-2*31^(1/2))/2, (2*31^(1/2)+12)/2}
x in { (12-2*31^(1/2))/2, (2*31^(1/2)+12)/2 }
