    Factor x2 - 7x + 8. @kinserkara can you tell me what two factors of 8 have product 8 and sum -7?

    you can't think of two such factors, right? for example here are the possibles: product=8 and sum=-7 8(1) but 8+1=? -8(-1) but -8-1=? 2(4) but 2+4=? (-2)(-4) but -2-4=?

    bc there are no factors that go into -7 and 8

    (x-8)(x+1) since there is an x squared, then you will have an x in each parenthesis. Now you need to find 2 numbers that will add to -7 AND multiply to -8. these numbers will each go in the parenthesis. In this problem, the two numbers are -8 and 1
