Oh That's Mine.I shifted the "2n" up wrongly.
how did he get 2n
He forgot to simplify the equation and he put the 2n at the top.
The m+n must always be multiplied by the same value.

2n came from out of the blue!?How did you get it?
The n from numerator suddenly go down to denominator...
Careless that put 2n at the top
How did he get 2n?
Careless mistake, the 2n came out from nowhere.
He put the 2n wrongly.
He probably misread the expressions.
2n was appearing from nowhere
I dont know how he/she got 2n
He accidentally put the 2n at the wrong place and is suppose to put it at the bottom.
The person did not show how he got 2n (which is wrong)
The student wrote 2n...careless mistake probably
how did m+n turn into m+2n?
did not show how to get 2n
How did the 2n land up there?
He cannot move the 2n up from the denominator to the numerator.
He shifted the n from the numerator down to the denominator
He shifted the 2n wrong.
