If a polynomial is not factorable using the product-sum method, does this mean that the polynomial is not factorable via use of the trial-and-error method?
I believe this is the case, but I just want to be sure.

U could always use the quadratic formula if your other methods are not working. Or try factoring by grouping first if the coefficient of A is more that 1...
