Answer

$\left (x+\frac{3}{5} \right )\left (x-\frac{2}{5} \right )$.

Work Step by Step

The given expression is $=x^2-\frac{6}{25}+\frac{1}{5}x$ Rearrange. $=x^2+\frac{1}{5}x-\frac{6}{25}$ Rewrite $\frac{1}{5}$ as $\frac{3}{5}-\frac{2}{5}$. $=x^2+\frac{3}{5}x-\frac{2}{5}x-\frac{6}{25}$ Factor. $=x\left (x+\frac{3}{5} \right )-\frac{2}{5} \left (x+\frac{3}{5} \right )$ $=\left (x+\frac{3}{5} \right )\left (x-\frac{2}{5} \right )$.
