Jun 19, 2024 · We determine the first root by hit and trial method and then proceed to determine other two roots by the same method as we get roots of a quadratic equation. Complete step-by-step answer: We start the solution by getting one root of the equation. x3 − 23x2 + 142x − 120 = 0 x 3 − 23 x 2 + 142 x − 120 = 0. by hit and trial method.
