You either need to list out all the possible solutions separately, as I did in previous example; or use a "plus-or-minus" in front of each possible solution, as I …
Web2 de may. de 2024 · We need to identify all real roots of f(x) = 2x3 + 11x2 − 2x − 2. In general, it is a quite difficult task to find a root of a polynomial of degree 3, so that it will be helpful if we can find the rational roots first. If x = p q is a rational root then p is a factor of − 2, that is p = ± 1, ± 2, and q is a factor of 2, that is q = ± 1 ... WebIt might be a rational. We don't know what y is. But y can take on any value, so at points it's going to be irrational. So we really just don't want a radical in the denominator. So what is this going to be equal to? Well, let's just multiply the numerator and the denominator by 2 square roots of y plus 5 over 2 square roots of y plus 5. This ...

Web6 de oct. de 2024 · 3 x 3 + x 2 + 17 x + 28 = 0. First we'll graph the polynomial to see if we can find any real roots from the graph: We can see in the graph that this polynomial has a root at x = − 4 3. That means that the polynomial must have a factor of 3 x + 4. We can use Synthetic Division to find the other factor for this polynomial.
