WebSo the hardest part of factoring a cubic polynomial in general is finding a real root. Once a root r r is found, the polynomial factors as f (x) = (x-r)g (x), f (x) = (x−r)g(x), where g (x) g(x) is quadratic, and quadratic polynomials can be factored easily via the quadratic formula. … WebFirst, we need to notice that the polynomial can be written as the difference of two perfect squares. 4x2 − y2 = (2x)2 −y2. Now we can apply above formula with a = 2x and b = y. (2x)2 −y2 = (2x −b)(2x +b) solve using calculator. Example 06: Factor 9a2b4 − 4c2. The binomial we have here is the difference of two perfect squares, thus ... Web1. 81 is an odd number and the cube root of 81 is an even number.

The next step is to put all of that together. This gets us 3x(2x + 3)(x - 2)(x - 2) Since you can no longer factor this equation, it is in simplest form. That means we just leave it like that. The second example is a little different: x^3 - 4x^2 + 6x - 24.
