You can factor this out by thinking of the factors of 56 that have a sum of -1. 7 and 8 are factors of 56 and to get a sum of -1, 8 should be negative. 7 + -8 = -1
So
factored out is (y+7x)(y-8x)
We can check this using FOIL
F = (y)(y) =
O = (y)(-8x) = -8xy
I = (7x)(y) = 7xy
L = (7x)(-8x) =

Some things you need in your respond is:
- Although the percentage might eventually round to 100%, it is not possible to have 100% of the phones working.
- This is because the model began when only 3 out of 10 phones were working, so there are 7 phones that were not working.
- In other words, the numerator and denominator of the expression are never the same, so the expression is never equal to 1 or 100%.
