  • A \((12 x+8 y+5 a+10 b)(12 x+8 y-5 a-10 b)\)
  • B \((12 x+8 y-5 a-10 b)(12 x+8 y-5 a-10 b)\)
  • C \(20(3 x+2 y-a-2 b)(3 x+2 y+a+2 b)\)
  • D \(20(3 x+2 y+a+2 b)(3 x+2 y+a+2 b)\).
Correct Answer: Option A
Explanation:
\(16(3 x+2 y)^{2}-25(a+2 h)^{2}\)
This is difference of two square i.e.
\([4(3 x+2 y)]^{2}-[5(a+2 b)]^{2}\)
\(=[4(3 x+2 y)+5(a+2 b)][4(3 x+2 y)-5(a+2 b)]\)
\(=(12 x+8 y+5 a+10 b)(12 x+8 y-5 a-10 b)\)
