The set of polynomials is closed under the operation of subtraction.
a: which equation illustrates this concept?
b: which statement correctly explains this concept?
select one answer for question a and one answer for question b.
b: the sum of the polynomials (3x+4) and (5xβ5) is a polynomial, 8xβ1, which shows closure under subtraction.
a: (3x+4)β(5xβ5)=81
b: the difference of the polynomials (3x+4) and (5xβ5) is not a polynomial. it is 81, which does not show there is closure under subtraction.
a: (3xβ4)+(2x+2)=5xβ2
a: (3x+4)+(5xβ5)=8xβ1
b: the product of the polynomials (3xβ4) and (2x+2) is a polynomial, 6x2β2xβ8, which shows closure under subtraction.
b: the sum of the polynomials (3xβ4) and (2x+2) is a polynomial, 5xβ2, which shows closure under subtraction.
a: (3xβ4)β(2x+2)=xβ6
a: (3xβ4)(2x+2)=6x2β2xβ8
b: the difference of the polynomials (3xβ4) and (2x+2) is a polynomial, xβ6, which shows closure under subtraction.
