Answer:

Step-by-step explanation:
A standard polynomial in factored form is given by:

Where <em>p</em> and <em>q</em> are the zeros.
We want to find a third-degree polynomial with zeros <em>x</em> = 2 and <em>x </em>= -8i and equals 320 when <em>x </em>= 4.
First, by the Complex Root Theorem, if <em>x</em> = -8i is a root, then <em>x </em>= 8i must also be a root.
Therefore, we acquire:

Simplify:

Expand the second and third factors:

Hence, our function is now:

It equals 320 when <em>x</em> = 4. Therefore:

Solve for <em>a</em>. Evaluate:

So:

Our third-degree polynomial equation is:

Answer:
12
Step-by-step explanation:
f(x) = -x^3 + x^2
Let x = -2
Evaluate the expression
f(-2) = -(-2)^3 + (-2)^2
= - (-2)*(-2) * (-2) + ( -2) * (-2)
= -(-8) + ( 4)
= 8 + 4
= 12
