Answer:
Closure property
Step-by-step explanation:
The closure property of polynomials for addition says that, if we add any two polynomials , the result is also a polynomial.
For is
[tex] {x}^{2} + 2[/tex]
is a polynomial.
[tex]x - 2[/tex]
is also a polynomial.
The sum of the two polynomials is
[tex] {x}^{2} + 2 + x - 2 = {x}^{2} + x [/tex]
The result:
[tex] {x}^{2} + x[/tex]
is also a polynomial.
