Answer:
Problems like this take practice.
Undoing the FOIL method I try to look for factors where the product of the last terms is 56.
(
?
+
8
)
(
?
+
7
)
=
0
The middle term is
−
5
x
so I take a guess that the first terms are
3
x
and
2
x
but I have to account for the negative signs so I have
(
3
x
+
8
)
(
2
x
−
7
)
=
0
3
x
+
8
=
0
or
2
x
−
7
=
0
3
x
=
−
8
x
=
−
8
3
2
x
=
7
x
=
7
2
