"WitrynaThis polynomial is considered to have two roots, both equal to 3. One learns about the "factor theorem," typically in a second course on algebra, as a way to find all roots that are rational numbers. One also learns how to find roots of all quadratic polynomials, using square roots (arising from the discriminant) when necessary. " - Imaginary numbers in polynomials
