यदि कोई समीकरण $E$ गुणा $F$ बराबर 0 ($E \times F = 0$) लिखा है, तो इसे हल करना किसे हल करने के समतुल्य हो जाता है?
AE = F = 1
BE + F = 0
CE - F = 0
DE = 0 या F = 0
Answer & Solution
Correct answer: D. E = 0 या F = 0
गुणनफल शून्य तभी होता है जब कोई गुणनखंड शून्य हो, इसलिए प्रत्येक गुणनखंड को अलग-अलग शून्य के बराबर रखा जाता है।
