Answer:
5/2
Step-by-step explanation:
Possible rational roots are ...
±(divisor of 9)/(divisor of 2)
So, the possibilities are ...
±1/2, ±1, ±3/2, ±3, ±9/2, ±9
The one on your list that is not among these is 5/2.
5/2 is not a possible rational root.

Answer:
x²(9x– 11)(9x + 11)
Step-by-step explanation:
81x⁴ – 121x²
The expression can be factorised as follow:
81x⁴ – 121x²
x² is common to both term. Thus:
81x⁴ – 121x² = x²(81x² – 121)
Recall:
81 = 9²
121 = 11²
Therefore,
x²(81x² – 121) = x²(9²x² – 11²)
= x²[(9x)² – 11²]
Difference of two squares
x²(9x– 11)(9x + 11)
Therefore,
81x⁴ – 121x² = x²(9x– 11)(9x + 11)
