Answer:
<h3>Polynomials are said to be <u>closed</u> under the operation of multiplication</h3>
Step-by-step explanation:
Because the product of two polynomials is always another polynomial, the polynomials are said to be <u>closed</u> under the operation of multiplication.
<h3>For :</h3>
The product of two polynomials is always another polynomial.
When two polynomials are multiplied, each and every term of the first polynomial is multiplied by each and every term of the second polynomial.
<h3>∴ Polynomials are said to be <u>closed</u> under the operation of multiplication.
