But however, if there were exactly 50 roots, the angular coefficients on the second from the right and second from the left intervals would have had different signs, and both of the intervals would have had roots.
Ngunit subalit, kung mayroong eksaktong 50 mga pinagmulan, ang angular coefficients sa ikalawa mula sa kanan at ang pangalawa mula sa kaliwa pagitan ay may ay iba't-ibang mga palatandaan, at pareho ng mga pagitan ay may ay may pinagmulan.
