Explanation:
Notice that the ratio between the first and second coefficients is not the same as that between the third and fourth.
That is:
27
54
≠
36
8
So this does not factor by grouping.
Note that the first and last terms are both perfect cubes:
27
x
3
=
(
3
x
)
3
8
=
2
3
So we might try
(
3
x
+
2
)
3
:
(
3
x
+
2
)
3
=
27
x
3
+
54
x
2
+
36
x
+
8
Yes - that's our factoring.
