Question

polynomial expressions consist of variables, coefficients, and ______.
the numerical factor of a term in a polynomial is known as the ______.
terms that have the same variables and exponents in a polynomial are called ______ terms.

Explanation:

1. Polynomials are constructed from variables, coefficients, and valid mathematical operations (addition, subtraction, multiplication, non-negative integer exponents).
2. The numerical factor paired with the variable part of a polynomial term is defined as the coefficient.
3. Terms in a polynomial that share identical variable(s) raised to the exact same exponents are classified as like terms.

Answer:

1. mathematical operations
2. coefficient
3. like
