How do you find rational zeros

WebOct 3, 2024 · The zero product property tells us that all the zeros are rational: 1, -3, and 1/2. If x - 1 = 0, then x = 1; if x + 3 = 0, then x = -3; if x - 1/2 = 0, then x = 1/2. Zeros are 1, -3, and... WebThis is where you can do a quick graph (especially if you have a graphing calculator), and see which of the list's value look good to try. For instance, comparing the graph below with the list above, you would probably do well to start looking for zeroes by plugging the values x = −3, −2, 1, and 2 into the polynomial.
