$\text{Terme - Additon - Subtraktion - Mulitiplikation - Division}\\ (-\frac{1}{3}x+\frac{1}{5})\cdot(-\frac{1}{4}x-2) \ $
$ \\ (-\frac{1}{3}x+\frac{1}{5})\cdot(-\frac{1}{4}x-2)= \\(-\frac{1}{3}x) \cdot (-\frac{1}{4}x)+(-\frac{1}{3}x) \cdot (-2)+\frac{1}{5} \cdot (-\frac{1}{4}x)+\frac{1}{5} \cdot (-2)=\\ \,\frac{1}{12}x^2+\frac{2}{3}x+(-\frac{1}{20}x)+(-\frac{2}{5})= \frac{1}{12}x^2+\frac{37}{60}x-\frac{2}{5}$
