They can be distinguished from each other by cleavage: feldspar has good cleavage, and quartz has no cleavage. That is, if the grain has a straight edge, it is more likely a feldspar, although exceptions occur. Polysynthetic twinning does not occur in quartz, and is a clear indicator of a feldspar when present.
