Answer:–or –+8x-16Step-by-step explanation:Given a second degree polynomial has a root 4 with multiplicity 2

That means,

4 is a repeating root of the polynomial.Any second degree polynomial has at most 2 real roots.⇒Both roots of the polynomial are 4.

and its

expression can be written asc· where c is a real number⇒c·(-8x+16)

⇒c-8cx+16c

Also, the leading coefficient is given as -1

So,

c = -1and the expression becomes (-1)-8·(-1)·x+16·(-1)

⇒

–+8x-16The correct answer is D, orJust got it right on Edge 2020, hope this helps!! 🙂
