The answer is ±3
$√(3\\)$

First, you should make one side of the quadratic 0. You can do this by subtracting 17 from both sides, making the equation

2/3x^2 - 18 = 0

To make everything an integer, you can multiply both sides by 3/2, making the equation

x^2 - 27 = 0

By adding 27 to both sides, you get

x^2 = 27

Now you are practically done! By taking the square root of both sides, you get

x = ±3
$√(3\\)$
