CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial. Adding polynomials creates another polynomial. Subtracting polynomials creates another polynomail. Multiplying polynomials creates another polynomial. Dividing polynomials does not necessarily create another polynomial.
Closure Property: This tells us that the result of the division of two Whole Numbers might differ. For example, 14 ÷ 7 = 2 (whole number) but 7 ÷ 14 = ½ (not a whole number).
In mathematics, the set of polynomials is not closed under division. This is because when you divide one polynomial by another, the result may not always be a polynomial. For instance, if we consider the polynomials P(x) = x2 and Q(x) = x.
Ing to the Associative property, when 3 or more numbers are added or multiplied, the result (sum or the product) remains the same even if the numbers are grouped in a different way. Here, grouping is done with the help of brackets. This can be expressed as, a × (b × c) = (a × b) × c and a + (b + c) = (a + b) + c.
CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial. Adding polynomials creates another polynomial. Subtracting polynomials creates another polynomail. Multiplying polynomials creates another polynomial.
Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.
It should be noted that the closure property of rational numbers holds true for addition, multiplication and subtraction.
The closure property for polynomials states that the sum, difference, and product of two polynomials is also a polynomial. However, the closure property does not hold for division, as dividing two polynomials does not always result in a polynomial. Consider the following example: Let P(x)=x2+1 and Q(x)=x.
When a integer is divided by another integer, the result is not necessarily a integer. Thus, integers are not closed under division.
Polynomials are NOT closed under division (as you may get a variable in the denominator).
