6\left(-x^{2}+64\right)
Factor out 6.
\left(8-x\right)\left(8+x\right)
Consider -x^{2}+64. Rewrite -x^{2}+64 as 8^{2}-x^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(-x+8\right)\left(x+8\right)
Reorder the terms.
6\left(-x+8\right)\left(x+8\right)
Rewrite the complete factored expression.
