@kinserkara
can you tell me what two factors of 8 have product 8 and sum -7?

Answer 9

umm

Answer 10

its prime!

Answer 11

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=?

Answer 12

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

Answer 13

right none of those sums are -7

Answer 14

(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
