Q. Factor the expression completely.

\newline

8 x^{3}+18 x

\newline

Answer:

Identify GCF of terms: Identify the greatest common factor (GCF) of the terms in the expression $8x^3$ and $18x$ . The GCF of $8$ and $18$ is $2$ . Both terms also have an $x$ in common, so the GCF is $2x$ .
Factor out GCF: Factor out the GCF from the expression. $2x(4x^2 + 9)$
Check for further factoring: Check if the remaining expression inside the parentheses can be factored further. $\newline$ The expression $4x^2 + 9$ is a sum of squares and cannot be factored over the real numbers.
