Which second degree polynomial function has a leading coefficient of –1 and root 4 with multiplicity 2?

-

or -+8x-16

Step-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 as c· where c is a real number

⇒c·(-8x+16)

⇒c-8cx+16c

Also, the leading coefficient is given as -1

So, c = -1

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

⇒-+8x-16
