A) \[\left( 2x+y \right)\left( 2x+y \right)\]
B) \[\left( 2x+y \right)\left( 2x-y \right)\]
C) \[\left( 2x-y \right)(2x-y)\]
D) \[\left( 2x+x \right)\left( 2y+x \right)\]
Correct Answer: A
Solution :
(a): \[4{{x}^{2}}+4xy+{{y}^{2}}=4{{x}^{2}}+2xy+2xy+{{y}^{2}}\] \[=2x\left( 2x+y \right)+y\left( 2x+y \right)=\left( 2x+y \right)\left( 2x+y \right)\]You need to login to perform this action.
