Can you continue from here?

No like I actually solved the problem. My solutions included complex numbers meaning one where x,y,z are real numbers doesn't exist.

I solved it by factorizing equation 2 and 3 to obtain the values of x+y+z(given in the question to be 0), xyz(=6) and xy+yz+xz(=7). Then used the cubic equation idea you mentioned.

1. You cannot treat an infinite product as a series unless you take the logarithm and study it.

2. Also, in using D'Alembert ratio test, you cannot make any conclusion if the ratio is one in this case it's better to use Cauchy Condensation Test or Bertrand's test.

Lol, OK just felt like trying the question out using the basic math I know.

If you are passionate about math, send me an email at goldpill1968@outlook.com, I can share some material that will help you beyond your school's curriculum.

I'll send you one immediately. I have a good collection of e-books but past questions have proved harder to get.

None of your answers are correct but I actually mean the square of the polynomial and not the composition.

Post your solution then.
