Answer:

Apologies for any confusion. Here's an example of a polynomial of degree 5 with the given zeros x = -1, 7, 6, and 3:

P(x) = (x + 1)(x - 7)(x - 6)(x - 3)(x - 3)

This polynomial has the given zeros and a degree of 5.

Explanation:

To find a polynomial of degree 5 with the given zeros x = -1, 7, 6, and 3, we can use the zero-product property and the fact that if a is a zero of a polynomial, then (x - a) is a factor of that polynomial.

Given zeros: x = -1, 7, 6, 3

To find a polynomial of degree 5, we need five linear factors. Using the given zeros, the polynomial can be expressed as:

P(x) = (x - (-1))(x - 7)(x - 6)(x - 3)(x - a)

To determine the last factor (x - a), we need one more zero. Since the degree of the polynomial is 5, we have one remaining zero.

Let's arbitrarily choose a = 2. Then the polynomial becomes:

P(x) = (x - (-1))(x - 7)(x - 6)(x - 3)(x - 2)

Expanding this polynomial will yield a degree-5 polynomial with the given zeros:

P(x) = (x + 1)(x - 7)(x - 6)(x - 3)(x - 2)

Note that there are multiple correct answers since we can choose different values for the last zero (x - a) as long as it is not one of the given zeros.
