    when you multiply out any of those "binomials" the last term, the number, will be what you get when you multiply the two constants together that has to give you \(-30\)

    to it could be A \((2b+5)(2b-6)\) or it could be C \((2b-5)(2b+6)\) because \(-5\times 6=-30\) it can't be the other two

    you can check which ones of the above give you a "middle term" of \(-13b\)

    you can guess it will be \((2b+?)(5b+?)\) and then reason that one of those has to be positive, the other negative, since the product is negative

    you get a bunch of choices, but since you really only have 4 possible answers, you can check the one that is right otherwise it is very tedious to go through all the possible combinations
