(Sorry if this in the wrong secton, still new here and not sure where else this would go)
I know the rules for factoring, but was wondering if there is a method/trick to handling problems where the numbers are large and obscure. For example, \(x^2+16x-1536\)
Obviously I knew the seperation of the two factors in their absolute form would be 16. I eventually was able to work my way to the answer of 32, -48 but not without a tedious process of picking a starting number (40) and working my way toward the number set.
The 16/1536 relation is not intuitive, is there a trick to arriving at 32,-48 more quickly?
Thanks
