It just how do i prove that
b^3 +b^2 +1 does not divide by 5
Im thinking this way,
cause i know that b^3 +b^2 +1 is not congruent to 0(mod5)
therefore we use contradition to prove it. I am just not sure how to use contradition? or maybe I am looking at this in a completely bad light? maybe there is another method?
