Which of the following is a polynomial with roots 2, 3i, and −3i? f(x) = x3 − 2x2 + 6x − 9 f(x) = x3 − 6x2 + 9x − 18 f(x) = x3 − 6x2 + 18x − 2 f(x) = x3 − 2x2 + 9x − 18

Step-by-step explanation:

The roots of the polynomial are .

This implies that are factors of the given polynomial.

The polynomial will have equation;

We expand using difference of two squares on the complex conjugates to get;

.

.

Recall that;

.

Expand using the distributive property to get;

.

We rewrite in standard form to obtain;

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512
