In the method that introduces fractions, $a^3 + 1$ is rewritten as $\frac{1}{27}(27a^3 + ____)$ before handling fractions.
When factoring $a^3 + 1$ using the direct method, the expression becomes $(a + 1)(a^2 - a + 1)$ after
The equivalent simplified expression after factoring out constants is achieved through $((3a)^2 - 3a \cdot 3 + ____)$.
The expression $a^3 + 1$ can be seen as a sum of .
After rewriting the expression with fractions, the factorization becomes $\frac{1}{27}(3a + 3)((3a)^2 - 3a \cdot 3 + 3^2)$. Simplifying gives .
