Haqiqatdan ham, agar OX o’qini kesib o’tsa, u holda Koshi masalasining yechimini yagonaligi buziladi, chunki y=0 (OX o’qi) ham (2) tenglamaning yechimi. Shunday qilib, quyidagi xulosaga kelamiz. Agar (2) tenglamani biron-bir yechimi (a,b) intervalni bitta nuqtasida nolga aylansa, u holda butun (a,b) intervalda nolga teng va aksincha (a,b) intervalni bitta nuqtasida nolga teng bo’lmasa, butun intervalda
noldan farqli.
