Find all zeros. One factor has been given
7)

To find all zeros of the polynomial , we can start by using synthetic division with the given factor . By substituting into the polynomial, we find the remainder is 0, confirming it is a factor. Then we divide by to get a quadratic polynomial, which can be further factored or solved using the quadratic formula.

The remaining factor can be calculated as follows: When you perform synthetic division, you find the resulting polynomial is . Now, setting this equal to zero gives us the remaining zeros. Solving leads to so .

In total, the zeros of the polynomial are . Happy zero-hunting!
