(7*x)/x-7+3 = x-(29/x)-3 // - x-(29/x)-3
29/x-x+(7*x)/x-7+3+3 = 0
29*x^-1-1*x^1+6*x^0 = 0
(6*x^1-1*x^2+29*x^0)/(x^1) = 0 // * x^2
x^1*(6*x^1-1*x^2+29*x^0) = 0
x^1
6*x-x^2+29 = 0
6*x-x^2+29 = 0
DELTA = 6^2-(-1*4*29)
DELTA = 152
DELTA > 0
x = (152^(1/2)-6)/(-1*2) or x = (-152^(1/2)-6)/(-1*2)
x = (2*38^(1/2)-6)/(-2) or x = (-2*38^(1/2)-6)/(-2)
