Factor $LaTeX: \displaystyle 72 x^{3} - 9 x^{2} + 48 x - 6$ .

Factoring out the GCF $LaTeX: \displaystyle 3$ from each term gives $LaTeX: \displaystyle 3(24 x^{3} - 3 x^{2} + 16 x - 2)$ . Grouping the first two terms and factoring out their GCF, $LaTeX: \displaystyle 3 x^{2}$ , gives $LaTeX: \displaystyle 3 x^{2}(8 x - 1)$ . Grouping the last two terms and factoring out their GCF, $LaTeX: \displaystyle 2$ , gives $LaTeX: \displaystyle 2(8 x - 1)$ . The polynomial now has a common binomial factor of $LaTeX: \displaystyle 8 x - 1$ . This gives $LaTeX: \displaystyle 3[3 x^{2} \left(8 x - 1\right) +2 \cdot \left(8 x - 1\right)] = 3\left(8 x - 1\right) \left(3 x^{2} + 2\right)$ .
