puckmaster87 Posted January 22, 2004 Share Posted January 22, 2004 Hey everyone. Can't figure out this problem - pretty urgent. Find the remainder when 3x^21-4x^18-4x^11-5x^4+1 is divided by x+1 I know the answer is -7, but why? Thanks. Link to comment Share on other sites More sharing options...

nuclei19 Posted January 23, 2004 Share Posted January 23, 2004 if u plug in -1 then u get it being divided by 0 which would be a number that doesnt exist. Link to comment Share on other sites More sharing options...
