How to solve cubic graphs
WebJan 27, 2024 · Here we will learn using an example how to solve a cubic polynomial. Example: Find the roots of the polynomial \ (2 {x^3} + 3 {x^2} – 11x – 6.\) Step 1: First, use the factor theorem to check the possible values by the trial-and-error method. Let \ (f (x) = 2 {x^3} + 3 {x^2} – 11x – 6\) \ (f\left ( 1 \right) = 2 + 3 – 11 – 6 \ne 0\) WebMay 26, 2024 · How to Solve Cubic Equations Using Graphs? Other than the factor theorem, you can try solving cubic equations using graphs. Start by drawing an accurate graph of the cubic equation. The points where the line of the graph intersects the x-axis will be the roots of your cubic expression.
