$x^3 â 7x^2 +7x + 15$. 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$.

1 For example, 6x 2 + 2x + 1 = 0 is a quadratic equation while 6x + 2 is not a quadratic equation. 2  Factoring-The process of breaking apart of an equation into factors (or separate terms) such that when the separate terms are multiplied together, they produce the original equation.3  For example, x 2 - x - 2 = (x+1)(x-2).efinitions. 1  Quadratic Equation-An equation that can be written in the form ax2 + bx + c = 0. 2  For example, 6x 2 + 2x + 1 = 0 is a quadratic equation while 6x + 2 is not a quadratic equation.
