Introduction. Just as you can perform the four operations on polynomials with one variable, you can add, subtract, multiply, and divide polynomials with more than one variable. The process is exactly the same, but you have more variables to keep track of.
The answer is C. Division. Addition and subtraction are closed for polynomials because the result of adding or multiplying two polynomials is always another polynomial. Division on the other hand is not closed for polynomials; if you divide two polynomials the result is not always a polynomial.
Polynomials will be closed under an operation if the operation produces new polynomial. When multiplication is applied on polynomials, the exponents of variables are added, Consequently, polynomials are always closed under multiplication.
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.
Among the common operations for polynomials—addition, subtraction, multiplication, and division—only division does not maintain closure.
Understand that when you subtract polynomials, you still get a polynomial, showing that the set of polynomials is 'closed' under subtraction.
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.
The closure property of addition states that when any two elements of a set are added, their sum will also be present in that set. The closure property formula for addition for a given set S is: ∀ a, b ∈ S ⇒ a + b ∈ S.
