Could anyone explain this 置く置かない to me please


I found the sentence

> けんかして嫁が出ていきました。 けんかの原因は、家に下宿人を **置く置かない** の件です

And I have a doubt about using of **置く置かない** How should it be translated ? and
How to use it I have never seen this grammar using before




> 「Verb in Affirmative Form + Same Verb in Negative Form」

is a common expression meaning:

> "(a discussion of) the pros and cons of [Verb]-ing" or
>
> "whether or not one should [Verb]"

Thus, the passage:

> 「けんかして嫁{よめ}が出{で}ていきました。 けんかの原因{げんいん}は、家{いえ}に下宿人{げしゅくにん}を **置{お}く置{お}かない**
> の件{けん}です。」

means:

> "My wife left home after the fight. The cause of our fight was regarding
> whether or not we should take in boarders/lodgers at our home."
