Factor the expression (x+4y) 2−9a2( x + 4 y ) ^ { 2 } - 9 a ^ { 2 }(x+4y) 29a2 completely.

A) (x+4y+3a) (x−4y−3a) ( x + 4 y + 3 a ) ( x - 4 y - 3 a ) (x+4y+3a) (x4y3a)
B) (x+4y−3a) 2( x + 4 y - 3 a ) ^ { 2 }(x+4y3a) 2
C) (x+4y+3a) 2( x + 4 y + 3 a ) ^ { 2 }(x+4y+3a) 2
D) (x+4y+9a) (x+4y−9a) ( x + 4 y + 9 a ) ( x + 4 y - 9 a ) (x+4y+9a) (x+4y9a)
E) (x+4y+3a) (x+4y−3a) ( x + 4 y + 3 a ) ( x + 4 y - 3 a ) (x+4y+3a) (x+4y3a)

Final Answer :
E
Explanation :
We can use the difference of squares formula to factor the expression as
(x+4y+3a)(x+4y−3a)−(9a2)=(x+4y+3a)(x+4y−3a−9a)+(3a)(−9a)(x+4y+3a)(x+4y-3a)-(9a^2)=(x+4y+3a)(x+4y-3a-9a)+(3a)(-9a)(x+4y+3a)(x+4y3a)(9a2)=(x+4y+3a)(x+4y3a9a)+(3a)(9a)
=(x+4y+3a)(x+4y−12a)=(x+4y+3a)(x+4y-12a)=(x+4y+3a)(x+4y12a)
Therefore, the answer is E.
