An example of a polynomial of a single indeterminate x is x2 − 4x + 7. An example with three indeterminates is x3 + 2xyz2 − yz + 1. <a href="https://mastodon.social/tags/Polynomials" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Polynomials</span></a> appear in many areas of mathematics and science.</p>
