If x + 1 / x = 3, (x ^ 3 + x-3 + 7) / (x ^ 4 + x ^ - 4 + 3)=

If x + 1 / x = 3, (x ^ 3 + x-3 + 7) / (x ^ 4 + x ^ - 4 + 3)=

As a result, we are going to find the following [x + X + 1 / x = 3 (x + 1 / x) (x + 1 / x) (178); = 3 (x + 1 / x) \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\3 × (7-1) = 18 (x ^ 3 + x-3 + 7) / (x ^ 4 + x ^ -...)
