$x^3 â 7x^2 +7x + 15$. 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$.

You don't always. You can use the quadratic formula x = -b +- sqrt(b^2 - 4ac). That doesn't require factoring. But if you have an equation factored into (x-r1)(x-r2) = 0 then you know immediately that the solutions are r1 and r2. I think you should read your textbook or class notes for the rest.or example, solving x^2 + 2x + 1 is easy with the quadratic formula, but knowing how to factor this equation makes solving for the roots quicker.
