Find zeros using synthetic division

WebNov 16, 2024 · Process for Finding Rational Zeroes. Use the rational root theorem to list all possible rational zeroes of the polynomial P (x) P ( x). Evaluate the polynomial at the numbers from the first step until we find a zero. Let’s suppose the zero is x = r x = r, then we will know that it’s a zero because P (r) = 0 P ( r) = 0. WebThese values can be tested by using direct substitution or by using synthetic division and finding the remainder. Synthetic 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 ...
