A trinomial is a polynomial with 3 terms. The degree of this polynomial must be '2'. In other words, there must be an exponent of '2' and that exponent must be the greatest exponet.

A trinomial is a polynomial with 3 terms. The degree of this polynomial must be '2'. In other words, there must be an exponent of '2' and that exponent must be the greatest exponet.

Examples:

- 3x² + 2x + 1
- 7x² + 4x + 4
- 5x² + 6x + 9

These are NOT trinomials

- 3x³ + 2x + 1
- this is not a trinomial because there is an exponent that is greater than 2

- 2x + 4
- this is not a trinomial because there is no exponent of 2
