Find the zeroes of the cubic polynomial
WebCubic polynomial - factoring method To solve cubic equations, we usually use the factoting method: Example 05: Solve equation 2x3 −4x2 − 3x +6 = 0. Notice that a cubic polynomial has four terms, and the most common factoring method for such polynomials is factoring by grouping. WebIt is not saying that the roots = 0. A root or a zero of a polynomial are the value (s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, …
