Factor \(\displaystyle 50 x^{3} - 50 x^{2} + 15 x - 15\).


Factoring out the GCF \(\displaystyle 5\) from each term gives \(\displaystyle 5(10 x^{3} - 10 x^{2} + 3 x - 3)\). Grouping the first two terms and factoring out their GCF, \(\displaystyle 10 x^{2}\), gives \(\displaystyle 10 x^{2}(x - 1)\). Grouping the last two terms and factoring out their GCF, \(\displaystyle 3\), gives \(\displaystyle 3(x - 1)\). The polynomial now has a common binomial factor of \(\displaystyle x - 1\). This gives \(\displaystyle 5[10 x^{2} \left(x - 1\right) +3 \cdot \left(x - 1\right)] = 5\left(x - 1\right) \left(10 x^{2} + 3\right)\).

\begin{question}Factor $50 x^{3} - 50 x^{2} + 15 x - 15$. 
    \soln{9cm}{Factoring out the GCF $5$ from each term gives $5(10 x^{3} - 10 x^{2} + 3 x - 3)$. Grouping the first two terms and factoring out their GCF, $10 x^{2}$, gives $10 x^{2}(x - 1)$. Grouping the last two terms and factoring out their GCF, $3$, gives $3(x - 1)$. The polynomial now has a common binomial factor of $x - 1$. This gives $5[10 x^{2} \left(x - 1\right) +3 \cdot \left(x - 1\right)] = 5\left(x - 1\right) \left(10 x^{2} + 3\right)$. }
