При заданной группировке определите выражения в скобках и затем разложите выражение на множители:

\(\displaystyle (72v^{\,9}z^{\,6}-30v^{\,16}y^{\,4}z^{\,2})+(132y^{\,5}z^{\,4}-55v^{\,7}y^{\,9})=\)

\(\displaystyle =6v^{\,9}z^{\,2} \,\big(\)[ ]\(\displaystyle \big)+11y^{\,5}\,\big(\)[ ]\(\displaystyle \big)=\)

\(\displaystyle =\big(\)[ ]\(\displaystyle \big)\big(\)[ ]\(\displaystyle \big)\)
