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. Witryna22 gru 2024 · Hence the polynomial formed. = x 2 – (sum of zeros) x + Product of zeros. = x 2 – 2x – 15. Example 3: Find a quadratic polynomial whose sum of zeros and product of zeros are respectively , – 1. Sol. Let the polynomial be ax 2 + bx + c and its zeros be α and β. (i) Here, α + β = and α.β = – 1. Thus the polynomial formed.
