Best ResponseYou've already chosen the best response.0the last number 4 has factors \(\pm1\), \(\pm 2\), \(\pm 4\) the first number 6 has factors \(\pm 1\), \(\pm2\), \(\pm 3\), \(\pm 6\) hence the factors of 6 will go with the factor of 4 to form the zeros of the polynomial but it is the denominator. I meant dw:1432874701462:dw

Best ResponseYou've already chosen the best response.0test 2, you get y =0, hence (x+2) is a factor of the polynomial. take long division to find other zeros. Are you allowed to use calculator?
