Factor $LaTeX: \displaystyle 28 x^{3} - 42 x^{2} + 4 x - 6$ .

Factoring out the GCF $LaTeX: \displaystyle 2$ from each term gives $LaTeX: \displaystyle 2(14 x^{3} - 21 x^{2} + 2 x - 3)$ . Grouping the first two terms and factoring out their GCF, $LaTeX: \displaystyle 7 x^{2}$ , gives $LaTeX: \displaystyle 7 x^{2}(2 x - 3)$ . Grouping the last two terms and factoring out their GCF, $LaTeX: \displaystyle 1$ , gives $LaTeX: \displaystyle 1(2 x - 3)$ . The polynomial now has a common binomial factor of $LaTeX: \displaystyle 2 x - 3$ . This gives $LaTeX: \displaystyle 2[7 x^{2} \left(2 x - 3\right) +1 \cdot \left(2 x - 3\right)] = 2\left(2 x - 3\right) \left(7 x^{2} + 1\right)$ .
