Question 257708
Let's do the last one first
we want factors of 12 that add up to 4 or have a difference of 4
since both -4y qnd -12 are negative the difference has to be 4
If they were both negative then the 12 would be +12
1,12
6,2
3,4


6 and 2
so the 6 is - and the 2 is plus
(x-6)(x+2)


(y-6) (y+2)

the first one is right
You aren't even close on the second one
-1*5 doesn't=6 
we need factors of 6 that add up to 5
both positive

BTW the website rules say
