Which one of the following is a simplification of 2-2x+1 / 4×2+4x+1 ?

Answer:

4) A

2- 2x+1 / 4×2+4x+1
We can simplify the denominator
2
4x

• 4x + 1 = (2x + 1)
  So we have
  2

2x+1

2
1
2x + 1
(2x+1)
Introduce the common denominator in the main expression. In this case, the common denominator would be (2x + 1)

2(2x+1)- 1 2x+1

4x+2-1 2x + 1

4x + 1

2x+1
