If a polynomial function f(x) has roots 3 and mc001-1.jpg, what must also be a root of f(x)?

The possible third root of the polynomial is -√7

Given a polynomial function with the roots 3 and √7, we need to find the third possible root of the polynomial.

If we look at the first two roots that were given, we can see that;

Note that some of the roots of a polynomial always occur as a conjugate pair especially the irrational roots.

Since the irrational root that we have is √7, hence its conjugate pair will be -√7.

Hence the possible third root of the polynomial is -√7

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
