How to Find All the Zeros of a Polynomial

Find every zero of a cubic or quartic: list rational candidates, narrow them with the rule of signs, test with synthetic division, and finish with the quadratic formula.

Use findings as a starting point

Automated inspection can surface evidence that deserves attention, but it cannot determine a person’s intent or guarantee that every hidden element was found. Verify important findings in the source document and preserve the original file when documenting a concern.
