Use synthetic division and the remainder theorem to find TWO rational zeros. Two rational zeros are x =
The reduced (or depressed) polynomial with both the factors corresponding to these zeros factored out is
By setting this equal to zero and using the quadratic formula, the remaining zeros of f are found to be:
