Trinomial

Trinomials are polynomials that contain three parts called terms, which are separated by plus and minus symbols. Here is a visual example of a trinomial:

$ax+by+c$

This is a linear expression, a component that makes up linear equations.

Examples

• $a{x}^2+bx+c$, a quadratic expression in its standard (normal) form, which happens to be a trinomial.
• Perfect square trinomials, $a^2\pm 2ab+b^2$.
