Answer:

  x = 2+1/3i or 2-1/3i

Step-by-step explanation:

The equation of interest can be written in vertex form as ...

  9(x -2)² +1 = 0

so its solutions can be found by subtracting 1, dividing by 9, taking the square root, then adding 2.

  x = 2 ± √(-1/9)

In the desired form, the zeros of the given expression are ...

  x = 2 +1/3i or 2 -1/3i
