+775 6x^2-47x+15 can be positive or negative or 0. We can factor \(6x^2-47x+15\) into \((3x-1)(2x-15)\). For (3x-1)(2x-15) to be prime, either (3x-1) or (2x-15) must be equal to 1 or -1. There are 4 scenarios.
1) 3x - 1 = 1. Simplifying, we have x = 2/3. Putting this into (2x-15), we have 4/3 - 15, which is not an integer or prime.
2) 3x - 1 = -1. Simplifying, we have x = 0. Putting this into (2x-15), we have -15. Absolute value makes it 15, which is not a prime.
3) 2x - 15 = 1. Simplyfying, we have x = 8. Putting this into (3x-1), we have 24-1 = 23. 23 is a prime.
4) 2x - 15 = -1. Simplifying, we have x = 7. Putting this into (3x-1), we have 21-1 = 20. 20 is not a prime.
The largest integer x such that |6x^2-47x+15| is prime is \(\boxed{8}\).
