If a polynomial function f(x) has roots -2+square root 8 and 9, what must be a factor of f(x)? 1. (x-(8-square root 2))
2. (x-(2-square root 8))
3. (x-(-2-square root 8))
4. (x-(-8+square root 2))

a is the correct

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
