We present a new practicable method for approximating all real zeros of polynomial systems using the resultants method. It is based on the theory of multi-resultants. We build a sparse linear system. Then, we solve it by the quasi-minimal residual method. Once our test function changes its ...
The second factor’s zeros are the missing two complex roots. This quadratic has no real roots since it does not have x-intercepts. Use the quadratic formula to find the roots. Example 3: Finding the Roots of a Polynomial Find the roots of x 2 + 2x + 3 with the quadratic formula: ...

We combine the known methods for univariate polynomial root-finding and for computations in the Frobenius matrix algebra with our novel techniques to advance numerical solution of a univariate polynomial equation, and in particular numerical approximation of the real roots of a polynomial. Our analysis...
