Разделите многочлен \(\displaystyle 12s^{\,4}\,-36s^{\,3}\,+\,18s\,-54\) на многочлен \(\displaystyle 3s-9\) в столбик:

\(\displaystyle -\)	\(\displaystyle \phantom{\,\,}12s^{\,4}-36s^{\,3}+18s-54\)				\(\displaystyle 3s-9\)
	[ ]				[ ]
	\(\displaystyle \phantom{35x^{\,4}+28x\,} -\)	[ ]
		[ ]
				\(\displaystyle 0\,\,\)

и запишите разложение:

\(\displaystyle 12s^{\,4}\,-36s^{\,3}\,+\,18s\,-54=(3s-9)\cdot(\)[ ]\(\displaystyle ).\)
