No, the number 5 is not a ploynomial.
No.
Quintinomial
The degree of a polynomial is identified by determining the highest exponent of the variable in the polynomial's expression. For example, in the polynomial (2x^3 + 4x^2 - x + 5), the highest exponent is 3, so the degree is 3. If the polynomial is a constant (like 5), its degree is 0, and if it's the zero polynomial, it's often considered to have no degree.
12x2 + 20x - 25 IS a polynomial that factors into (2x + 5)(6x - 5)
The x^5 at the beginning makes the degree of the polynomial 5.

The term in a polynomial without a variable is called a "constant term." It represents a fixed value and does not change with the variable's value. For example, in the polynomial (3x^2 + 2x + 5), the constant term is (5).
