WebSynthetic division is the better method because if a zero is found, the polynomial can be written in factored form and, if possible, can be factored further, using more traditional methods. Example 2 Find rational zeros of f(x) = 2 x 3 … WebWhen you have been provided with a complex number for one of the zeroes of a polynomial, and after you've divided out that factor, your next step will be to divide out the conjugate. That is, when they've given you a + bi as one zero, then your next step will be to divide out a − bi.
