Answer:

  x = {7, 1, -4}

Step-by-step explanation:

Dividing the given factor from the polynomial using synthetic division, we get ...

  f(x) = (x -7)(x^2 +3x -4)

Factoring the quadratic* gives ...

  f(x) = (x -7)(x -1)(x +4)

The zeros are the values of x that make these factors be zero:

  x = {7, 1, -4}

_____

* The constants in the binomial factors are factors of -4 that have a sum of +3. Those are (-1)(4) = -4. -1+4 = 3.
