We can Split the Middle Term of this expression to factorise it.
In this technique, if we have to factorise an expression like
a
x
2
+
b
x
+
c
, we need to think of 2 numbers such that:
N
1
⋅
N
2
=
a
⋅
c
=
4
⋅
4
=
16
and
N
1
+
N
2
=
b
=
8
After trying out a few numbers we get
N
1
=
4
and
N
2
=
4
4
⋅
4
=
16
and
4
+
4
=
8
x
2
+
8
x
+
16
=
x
2
+
4
x

16
=
x
(
x

)
(
x
