Explanation:
In algebra, a polynomial is an expression consisting of variables (such as 'x', 'y', or 'p') raised to non-negative integer powers, combined with coefficients (constants), and combined using addition and subtraction operations. The terms within a polynomial are separated by addition or subtraction signs.
The degree of a polynomial is determined by the highest exponent (power) of the variable in the polynomial. It represents the highest power to which the variable is raised. For example, in the polynomial 3p^3 + 2p^2 + 19p - 5, the highest power of the variable 'p' is 3, so the degree of the polynomial is 3.
The number of terms in a polynomial refers to the separate parts that are added or subtracted. In the polynomial 3p^3 + 2p^2 + 19p - 5, there are four terms: 3p^3, 2p^2, 19p, and -5.
Let's break down the classification of each polynomial:
