Answer:
f(x) = x^6 -10x^5 +89x^4
Step-by-step explanation:
For a given zero p with multiplicity n, one of the factors of the polynomial will be (x -p)^n. If the polynomial has real coefficients, then the complex zeros come in conjugate pairs.
The factored form of your polynomial is ...
f(x) = (x -(5 -8i))(x -(5 +8i))(x -0)^4
f(x) = ((x -5)^2 -(8i)^2)(x^4) = (x^2 -10x +89)(x^4)
f(x) = x^6 -10x^5 +89x^4

Step-by-step explanation:
She would have to take 5.29 miles to save round-trip if she had taken the direct route.
<h3>What is the
Pythagoras theorem?</h3>
The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
The direct route from Marta's apartment to work is a road that is a straight line. The road is closed for repairs.
Marta had to drive 8 miles west and then 6 miles south to get to work. She returned home by the same route.
Let's consider x to be the direct route.
By Pythagoras theorem, we can find the direct route
Thus, She would have to take 5.29 miles to save round-trip if she had taken the direct route.
