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

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