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.
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.
Closure Property: When something is closed, the output will be the same type of object as the inputs. For instance, adding two integers will output an integer. Adding two polynomials will output a polynomial. Addition, subtraction, and multiplication of integers and polynomials are closed operations.

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.
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 Property: The closure property states that the sum of two polynomials is a polynomial. This means that if you add any two polynomials together, the result will always be another polynomial. For example, if you have the polynomials P(x)=x2+2 and Q(x)=3x+4, their sum P(x)+Q(x)=x2+3x+6 is also a polynomial.
Closure property holds for addition and multiplication of whole numbers. Closure property of whole numbers under addition: The sum of any two whole numbers will always be a whole number, i.e. if a and b are any two whole numbers, a + b will be a whole number. Example: 12 + 0 = 12. 9 + 7 = 16.
Closure Property of Addition The set of real numbers, natural numbers, whole numbers, rational numbers, and integers are closed under addition. Real number (a, b are real numbers.) Rational number (a, b are real numbers.) Integer (a, b are integers.)
When adding polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the sum has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under addition.
