SUMMARY

The congruence equation x^11 + 3x^10 + 5x ≡ 2 (mod 11) has solutions based on the condition that gcd(a, m) must divide c. In this case, since 11 divides the expression x^11 + 3x^10 + 5x - 2, and testing x = 1 yields gcd(11, 9) = 1, which divides 2, a solution exists. The approach to find specific solutions involves checking integers from 1 to 10 to identify which values satisfy the congruence.

Homework Statement



Determine if the congruence has solutions. If it does, determine the complete solution

x^11 + 3x^10 + 5x ≡ 2 (mod 11)

Homework Equations





The Attempt at a Solution



i know that 11 | x^11 + 3x^10 + 5x -2

and where ax≡c (mod m) has a solutioon iff gcd(a,m) | c

and that's about it

i also know if x =1...then the gcd(11,9) | 2 ...meaning there is a solution

The only thing I can think about is checking each number 1-10 to see which has a remainder of 2.
