Step-by-step explanation:
Now we need to determine the factors which multiply to 48 and when subtracted are -2:
1
×
−
48
=
−
48
;
1
−
48
=
−
47
<- this is not the factor
2
×
−
24
=
−
48
;
2
−
24
=
−
22
<- this is not the factor
3
×
−
16
=
−
48
;
3
−
16
=
−
13
<- this is not the factor
4
×
−
12
=
−
48
;
4
−
12
=
−
8
<- this is not the factor
6
×
−
8
=
−
48
;
6
−
8
=
−
2
<- this IS the factor
