$2\left( 4x^8+6x^4+9 \right)$
$\bf{\text{Solution Outline:}}$ Get the $GCF$ of the given expression, $8x^8+12x^4+18 .$ Divide the given expression and the $GCF.$ Express the answer as the product of the $GCF$ and the resulting quotient. $\bf{\text{Solution Details:}}$ The $GCF$ of the constants of the terms $\{ 8,12,18 \}$ is $2$ since it is the highest number that can divide all the given constants. Factoring the $GCF= 2 ,$ the expression above is equivalent to \begin{array}{l}\require{cancel} 2\left( \dfrac{8x^8}{2}+\dfrac{12x^4}{2}+\dfrac{18}{2} \right) \\\\= 2\left( 4x^8+6x^4+9 \right) .\end{array}
