Advice needed: biwire speaker cables used as single wire speaker cable?

Hello, I have a chance to get a pair of good 2nd hand true biwire speaker cables, but my speakers only have one positive and one negative terminals on each side. Would it make sense to connect the biwire cables to my speakers that only have one positive and one negative terminals on each side?  The question may sound stupid but  these cables are not available on the 2nd market often, so I really want to get them. Thanks much for yours valuable advice.
