Question

If a polynomial function f(x) has roots 0, 4, and 3+ /11, what must also be a root of f(x)?

Answer 1

Answer:

3 - $\sqrt{11}$

Step-by-step explanation:

Assuming the root given is 3 + $\sqrt{11}$

Radical roots occur in conjugate pairs, thus

if 3 + $\sqrt{11}$ is a root , then 3 - $\sqrt{11}$ is also a root
