Best ResponseYou've already chosen the best response.0Here's a some hint to do these type of factoring problems: 1If the last term is negative (like #1 and 2), your factors will most likely be of the form (x+y)(xz) 2If the last term is positive, then your factors will be of the form (x+y)(x+z) OR (xy)(xz)
