WebAnswer: For every cubic equation there exist at-least one real root . There are many methods for finding the real root with some initial approximation using any of the method given below: * Bisection Method * Regula - Falsi * Secant Method * Newton- Raphson Method * Chebyshev Method * Muti... WebFeb 10, 2024 · The roots of a cubic equation correspond to the points where the graph of the cubic polynomial crosses the horizontal axis.However, this method is not very precise! You should rather treat these points as guesses and verify them algebraically. If your graph appears to cross the x-axis at q, try dividing your cubic polynomial by x- q.If there is no …
