Select all of the following that are potential roots of p(x) = x4 − 9×2 − 4x + 12? 0 ±2 ±4 ±9 1/2 ±3 ±6 ±12?

1 Answer

  • It would be a factor of the constant term over a factor of the coefficient of the high-degree term.

    So we’re dealing with 12 and 1, so that leaves these as your possible rational roots:

    ±1, ±2, ±3, ±4, ±6, ±12
