You can try all the possible values for x to see whether the congruence holds (a)(i) Put x=0,1,2,3,4,5 (ii) Put x=0,1,2,3,...,10 factorize the polynomial may help but you have to solve it carefully There are 4 conditions:
The second is more straightforward to solve by factorising because it is and 11 is prime.
