| Naming PolynomialsPolynomials look like this… - 4x² + 3x – 1
- 8
- 9xy²
- 3x – 2y
- x³
- 25x² - 4
- 5x³ – 4x + 7
A Polynomial can be named in two ways Names by the number of terms: 1 term : monomial Here are some monomials… 3x² 7xy x 8 ½x 2 terms : Binomial Here are some binomials… 5x + 1 3x² - 4 x + y 3 terms : Trinomial Here are some trinomials… 7x² + 2x – 10 There is no special name for polynomials with more than 3 terms, so we just refer to them as polynomials (the prefix “poly” means many ) Examples Name each expression based on - 5x + 1
- 7x²
- 5x – 2xy + 3y
- 6x³ - 9x² + x – 10
- 5x + 1 Binomial
- 7x² Monomial
- 5x – 2xy + 3y Trinomial
- 6x³ - 9x² + x – 10 Polynomial
Finding Degrees In order to name a polynomial by degree, you need to know what degree of a polynomial is, right?? Finding Degrees Definition of Degree The degree of a monomial is the sum of the exponents of its variables. For example, The degree of 7x³ is 3
