Answer 1

Answer:

Step- The factors of a² + 4b²+ 4b – 4ab – 2a – 8

= a² + 4b² – 4ab – 2a + 4b – 8

= (a – 2b) 2 – 2(a – 2b) – 8

Let, (a – 2b) = x

∴ The given expression = x2 – 2x – 8

= x2 – 4x + 2x – 8

= x(x – 4) + 2(x – 4)

= (x – 4) (x + 2)

Putting the value of x , we get

∴ a²+ 4b² + 4b – 4ab – 2a – 8 = (a – 2b – 4) (a – 2b + 2)

Therefore , required answer will be (a – 2b – 4) (a – 2b + 2)

The correct answer is

option 1.(a-2b-4)(a-2b+2)
