Factorising cubics gcse
WebLet us factorize a cubic polynomial using the grouping method to understand the process of factoring cubic polynomials. Example 1: Factorize the cubic polynomial f (x) = x 3 − 5x 2 + 4x − 20. Solution: To factorize the polynomial f (x), we will divide it into groups. f (x) = x 3 − 5x 2 + 4x − 20 = (x 3 − 5x 2) + (4x − 20) WebSketching Cubics. Firstly, identify whether the cubic is positive or negative. Then, substitute x = 0 into the cubic expression to identify the y -intercept. Next, factorise if possible and set y = 0 to identify the roots. Note that, in y = x ( x + 1) 2 for example, x = − 1 is a repeated root and the curve must touch the x-axis at x = − 1.

First, we need to find which number when substituted into the equation will give the answer zero. Therefore ( x - 1 ) is a factor. Factorise the quadratic WebThe factor theorem is a very useful result about polynomials. A polynomial is an algebraic expression consisting of a finite number of terms, with non-negative integer indices only. At A level you will most frequently use the factor theorem as a way to simplify the process of factorising polynomials.
