Symmetric Polynomial (Tomato subjective 61)

Problem: solve
\({{6x}^{2}} \) – 25x + 12 + \({\frac{25}{x}} \) + \({\frac{6}{x^2}} \) = 0.
Solution: \({{6x}^{2}} \) – 25x + 12 + \({\frac{25}{x}} \) + \({\frac{6}{x^2}} \) = 0
= 6( \({x^2} \) + \({\frac{1}{x^2}} \)) – 25(x – \({\frac{1}{x}} \)) +12 = 0
= 6 (x – \({\frac{1}{x}})^2 \) – 25 (x – \({\frac{1}{x}} \)) + 24 = 0
= (x – \({\frac{1}{x}} \)) = \({\frac{25\pm {\sqrt49}}{12}} \) = \({\frac{3}{2}} \) or \({\frac{8}{3}} \)
