$x^3 â 7x^2 +7x + 15$. Iâve been trying to figure out how to factor cubic equations by studying a few worksheets online such as the one here and was wondering is there any generalized way of factoring these types of equations or do we just need to remember a bunch of different cases.x^3 â 7x^2 +7x + 15$.

If youâre solving an equation, you can throw away any common constant factor. But if youâre factoring a polynomial, you must keep the common factor. Example: To solve 8xÂ² + 16x + 8 = 0, you can divide left and right by the common factor 8. The equation xÂ² + 2x + 1 = 0 has the same roots as the original equation.tep 4. Find One Factor or Root. This step is the heart of factoring a polynomial or solving a polynomial equation. There are a lot of techniques that can help you to find a factor. Sometimes you can find factors by inspection (see the first two sections that follow).
