WitrynaA complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. This way, a complex number is defined as a polynomial with real coefficients in the single indeterminate i, for which the relation i 2 + 1 = 0 is imposed. Based on this … WitrynaWe use the Descartes rule of Signs to determine the number of possible roots: Positive real roots. Negative real roots. Imaginary roots. Consider the following polynomial: 3×7 + 4×6 + x5 + 2×4 – x3 + 9×2 + x + 1. Let’s find all the possible roots of the above polynomial: ADVERTISEMENT. First Evaluate all the possible positive roots by ...
