Final answer:
To find a polynomial of degree 3 with real coefficients and zeros, use the fact that if a polynomial has a zero at x = a, then it has a factor of (x - a). The polynomial will have three factors, corresponding to the three zeros.
Step-by-step explanation:
To find a polynomial of degree 3 with real coefficients and zeros, we can use the fact that if a polynomial has a zero at x = a, then it has a factor of (x - a). Therefore, the polynomial will have three factors, corresponding to the three zeros.
Let's say the zeros are a, b, and c. Then the polynomial can be written as (x - a)(x - b)(x - c).
For example, if the zeros are 1, 2, and 3, then the polynomial would be (x - 1)(x - 2)(x - 3).
