Which of the following shows that polynomials are closed under addition when two polynomials 4x + 6 and 2x2 − 8x − 4 are added? 2x2 − 4x + 2 will be a polynomial 2x2 − 4x + 2 may or may not be a polynomial 2x2 − 12x − 10 will be a polynomial 2x2 − 12x − 10 may or may not be a polynomial

The first option is the answer.

Hi there! i am actually on this question too lolso when you add them you get 2x^2-4x+2  so that narrows it down to the first two options  so now you have to figure out if it is a polynomial  a polynomial is a combination of terms it does not contain variables raised to negative or fractional exponents, variables, in the denominator or under a radical or any other features  so it is the second option because 2x^2 is raised so it may or may not be a polynomial i hope this !
