A) \[2{{y}^{3}}-8{{x}^{2}}y+3x{{y}^{2}}-2{{x}^{3}}\]
B) \[2{{x}^{3}}-2x{{y}^{2}}-{{x}^{2}}y-2{{y}^{3}}\]
C) \[-11{{x}^{2}}y\]
D) \[11{{x}^{2}}y\]
Correct Answer: C
Solution :
\[\underset{\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_}{\mathop{\underset{-11{{x}^{2}}y}{\mathop{\underset{\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_}{\mathop{\begin{align} & \,\,\,\,\,\,\,\,\,{{x}^{3}}-6{{x}^{2}}y-x{{y}^{2}}-{{y}^{3}} \\ & (-)\,\,\,\,{{x}^{3}}+5{{x}^{2}}y-x{{y}^{2}}-{{y}^{3}} \\ \end{align}}}\,}}\,}}\,\]
