A) \[\therefore \,\,Coefficient of \,y =2{{x}^{2}}\]
B) \[\therefore \,\,Coefficient of \,x=2{{y}^{2}}\]
C) \[\therefore \,\,Coefficient of \,y=2x\]
D) \[Coefficient of \,x=2{{y}^{2}}\]
Correct Answer: A
Solution :
Sol. We have, \[\left( 3{{x}^{2}}y+2{{y}^{2}}+5 \right)-\left( {{x}^{2}}y+{{y}^{2}}+3 \right)=3{{x}^{2}}y+2{{y}^{2}}+5-{{x}^{2}}y\,-{{y}^{2}}-3\] \[=\,\,2{{x}^{2}}y+{{y}^{2}}+2\] \[\therefore \,\,Coefficient of \,y =2{{x}^{2}}\]You need to login to perform this action.
