The expression \(8b^3 + 27c^3\) is a sum of cubes. This can be factored using the sum of cubes formula, which is:

\[
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
\]

In this case, we can identify:

\[
a = 2b \quad \text{and} \quad b = 3c
\]

Applying the sum of cubes formula:

\[
8b^3 + 27c^3 = (2b)^3 + (3c)^3 = (2b + 3c)\left((2b)^2 - (2b)(3c) + (3c)^2\right)
\]

Now, let's expand and simplify the expression inside the parentheses:

1. \((2b)^2 = 4b^2\)
2. \((2b)(3c) = 6bc\)
3. \((3c)^2 = 9c^2\)

So the factored form of the expression is:

\[
8b^3 + 27c^3 = (2b + 3c)(4b^2 - 6bc + 9c^2)
\]
