Разделите многочлен \(\displaystyle u^{\,3}+5u^{\,2}-18u-18\) на многочлен \(\displaystyle u^{\,2}+8u+6\) в столбик:

\(\displaystyle -\)	\(\displaystyle \phantom{\,\,}u^{\,3}+5u^{\,2}-18u-18\phantom{zz}\)				\(\displaystyle u^{\,2}+8u+6\)
	[ ]				[ ]
	\(\displaystyle \phantom{ x\,\,} -\)	[ ]
		[ ]
		\(\displaystyle 0\phantom{zz}\)

и запишите разложение:

\(\displaystyle u^{\,3}+5u^{\,2}-18u-18=(\,u^{\,2}+8u+6)\cdot \big(\)[ ]\(\displaystyle \big){\small . }\)
