Witryna16 lis 2024 · Here’s an example of a polynomial: 4x + 7. 4x + 7 is a simple mathematical expression consisting of two terms: 4x (first term) and 7 (second term). In algebra, terms are separated by the logical operators + or -, so you can easily count how many terms an expression has. 9x 2 y - 3x + 1 is a polynomial (consisting of 3 terms), too.
