Trinomial

Trinomials are polynomials that consist of three terms, separated by plus and minus symbols. An example of a trinomial is:

${\displaystyle ax+by+c}$

This is a linear expression, which is a component of linear equations.

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

• Monomial
