We have two binomials, so we can use the highly useful mnemonic FOIL to helps us:
Multiply the first terms:
x
⋅
x
=
x
2
Multiply the outside terms:
x
⋅
4
=
4
x
Multiply the inside terms:
7
⋅
x
=
7
x
Multiply the last terms:
7
⋅
4
=
28
Thus,
(
x
+
7
)
(
x
+
4
)
multiplies out to
x
2
+
4
x
+
7
x
+
28
, which can be simplified to:
x
2
+
11
x
+
28
