Разделите многочлен \(\displaystyle y^{\,3}-3y-2\) на многочлен \(\displaystyle y-2\) в столбик:

\(\displaystyle -\)	\(\displaystyle \phantom{\,\,}y^{\,3}-3y-2\)				\(\displaystyle y-2\)
	[ ]				[ ]
	\(\displaystyle -\)	[ ]
		[ ]
		\(\displaystyle \phantom{ xx} -\)		[ ]
				[ ]
				\(\displaystyle 0\)

и запишите разложение:

\(\displaystyle y^{\,3}-3y-2=(\,y-2)\cdot \big(\)[ ]\(\displaystyle \big).\)
