(x^7+x^5+x^3)/(x^6+x^5+x^4)=81/27 x=2 ± Sqrt[3]

[@ghaidabarghouthi1403]

You have done extra steps, just divide 81/27=3 from the beginning

[@vijaymaths5483]

Yes ,I know thanks for sharing 👍 your valuable feedback 🌺

Porque as raízes complexas não servem? (x + 1/x = -1) se não foi dado o conjunto prè especificado? (Why are complex roots no good? (x + 1/x = -1) if the pre-specified set was not given?)

{x^7+x^7 ➖ }+{x^5+x^5 ➖ }+{x^3+x^3 ➖ }/(x^6+x^6 ➖}+(x^5+x^5 ➖}+{x^4+x^4 ➖}= 30x^6/30x^6=1x1 (x ➖ 1x+1). 9^9/3^3 3^2^3^2/1^1 1^1^3^1 (x ➖ 3x+1)

It is surprising that 81/27 is continued throught out instead of writing it as 3. I don't understand the reason!
