Answer:
(a) ±1/9, ±2/9, ±1/3, ±4/9, ±2/3, ±1, ±4/3, ±2, ±4
Step-by-step explanation:
The leading coefficient is 9; the constant is 4. The rational roots will be ...
±(divisor of 4)/(divisor of 9)
The divisors of 4 are 1, 2, 4. The divisors of 9 are 1, 3, 9. Then the rational roots can be any of ...
±1/9, ±2/9, ±1/3, ±4/9, ±2/3, ±1, ±4/3, ±2, ±4
