If a polynomial function f(x) has roots 0, 3, and 2+ V5, what must also be a root of f(x)?
-2-sqrt15
2-sqrt15
15-sqrt 2
15+sqrt 2

Option B.

Step-by-step explanation:

Note: Given roots are not in proper format.

Consider the polynomial function f(x) has roots 0, 3, and .

According to irrational root theorem if is root of a polynomial P(x), then is also a root of polynomial P(x).

Since is an irrational root of the function f(x). By irrational root theorem is also a root of function f(x).

Therefore, the correct option is B.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total
