## Precalculus: Mathematics for Calculus, 7th Edition

Type: trinomial Terms: -2$x^2$, 5x, -3 Degree: 2
The type of the polynomial is a monomial if it has one term, a binomial if it has two terms, and a trinomial if it has three terms. This polynomial has 3 terms, therefore it is a trinomial. The terms are simply the values separated by plus and minus signs: -2$x^2$, 5x, -3. The degree is just the highest exponent of the variable in any of the terms, and if no x is present, the degree is 0. Therefore, the degree of this polynomial is 2.
