Use the Product Rule and Chain Rule:
f
'
(
x
)
=
(
5
x
+
1
)
2
⋅
2
+
2
(
5
x
+
1
)
⋅
5
⋅
(
2
x
−
1
)
.
This can be simplified in a couple ways. Probably the most useful way is to leave it in a factored form:
f
'
(
x
)
=
2
(
5
x
+
1
)
(
5
x
+
1
+
10
x
−
5
)
=
2
(
5
x
+
1
)
(
15
x
−
4
)
That way, you can quickly see the critical points of
f
(
x
)
are
x
=
−
1
5
and
x
=
4
15
.
You can get your answer with it
