WebWe'll divide r(x) by that factor and this will give us a cubic (degree 3) polynomial. We'll find a factor of that cubic and then divide the cubic by that factor. Then we are left with a trinomial, which is usually relatively straightforward to factor. Trial 1: We try substituting x = 1 and find it's not successful (it doesn't give us zero). Web3 You need to solve the equation x 5 + 2 x 3 + x − 1 = y for x. Unfortunately, such quintic equations are known to have no closed-form solution in general, and this one does not escape the rule. Anyway, there is a little backdoor, as a quintic can be (after painful computation) reduced to the form known as Bring Quintic Form x 5 − x − a = 0.
