To solve the equation x^2 ≡ 17 (mod 19), we need to find the square roots of 17 in the field of integers modulo 19.

Step 1: Check if 17 is a quadratic residue modulo 19. This can be done by checking if the Legendre symbol (17/19) is 1. If it is, then 17 is a quadratic residue modulo 19 and has square roots.

Step 2: Compute the Legendre symbol (17/19). This can be done using the properties of the Legendre symbol.

Step 3: If the Legendre symbol (17/19) is 1, then 17 is a quadratic residue modulo 19 and has square roots.

Step 4: Find the square roots of 17 modulo 19. This can be done by trying all the integers from 1 to 18 and checking if their square modulo 19 is 17.

Step 5: The solutions to the equation x^2 ≡ 17 (mod 19) are the square roots of 17 modulo 19.

After performing these steps, we find that the solutions to the equation x^2 ≡ 17 (mod 19) are x = 11 and x = 8.
