==Trinomial--3 Terms==

There are three possibilities for factoring a trinomial depending on which type of trinomial it is.

===Monic Trinomials===--There
A ismonic trinomial has a 1 as the leading coefficient.<br />

<math>x^2+bx+c=(x+d)(x+e),</math>

<br /><br />

===Non-Monic Trinomials=== (There
A isnon-monic trinomial has a constant other than 1 as the leading coefficient.)<br />

<math>ax^2+bx+c=(mx+p)(nx+q)</math><br />

where <math>mn=a</math>, <math>pq=c</math>, and <math>mq+pn=b</math><br />
