Apolynomial function has -5√3i as a root. which of the following must also be a root of the function? -5-√3i -5+√3i 5-√3i 5+√3i

-5+√3i  is the given root so -5-√3i  must be the other root

Step-by-step explanation:

We know that complex roots must come in pairs. The pairs are complex conjugates.  (a+bi)  and (a-bi)

You are missing a sign between -5 and the square root

So if - 5+ sqrt(3) i  is a root, then -5 - sqrt(3) i   must be a root  

if -5 - sqrt(3)i   is a root, then -5 + sqrt(3)i   must be a root.

I will assume you missed a + sign

-5+√3i  is the given root so -5-√3i  must be the other root

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
