Дополните правильные варианты группировки слагаемых и разложите на множители в произведение двучлена и трехчлена:

\(\displaystyle -16p^{\,3}-\color{red}{36p^{\,8}}-\color{blue}{8p^{\,7}}-\color{red}{18p^{\,12}}-\color{blue}{28}-63p^{\,5}=\)

\(\displaystyle =(-\color{red}{18p^{\,12}}-\color{red}{36p^{\,8}}\)[?|+|-][ ]\(\displaystyle )+(-\color{blue}{8p^{\,7}}\)[?|+|-][ ]\(\displaystyle -\color{blue}{28})=\)

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