Finding imaginary roots of polynomials

WebA given quadratic equation ax2 + bx + c = 0 in which b2 -4ac < 0 has two complex roots: x = ,. Therefore, whenever a complex number is a root of a polynomial with real coefficients, its complex conjugate is also a root of that polynomial. As an example, we'll find the roots of the polynomial x5 - x4 + x3 - x2 - 12x + 12 . complexroots WebThere is no imaginary root. Sometimes, roots turn out to be the same (see discussion above on "Zeroes & Multiplicity"). That is what is happening in this equation. So, the equation degrades to having only 2 roots. If you factor the polynomial, you get factors of: -X (X …

In a … WebThis trick can be used to visualize the roots of any complex function f. Just write it in the form f ( x + i y) = u ( x, y) + i v ( x, y) and plot the solution sets to u ( x, y) = 0 and v ( x, y) = 0. Then the roots will correspond to the intersections of these two curves. Share Cite Follow answered May 23, 2016 at 21:43 John Gowers 24.1k 4 62 100
