4

Answer 1

2x+1 is the answer

Answer 2

2(2x+1)

Answer 3

I thought it was 2(2x + 1) too

Answer 4

That is the wrong answer

Answer 5

Since you can factor the numerator and then divide the 2

Answer 6

it comes to

2x - 5
-----
2(2x+1)

Answer 7

The numerator is 2x-2

Answer 8

since 2x+1-3=2x-2

Answer 9

And then factor the numerator as 2(x-1)

Answer 10

and then divid the 2s which results in (x-1)/(2x+1)

Answer 11

Do u get it?

Answer 12

My ending result was (2x - 5) / 2 (2x + 1)

Answer 13

Why did you get 2x-5?

Answer 14

2x+1 -3=2x-2

Answer 15

Wait How did you get 2x - 2

Answer 16

1(2x+1)=2x+1 and -3(1)=-3
2x+1-3=2x-2
