alleryax + b = 0 ला नेमकी एकच उकल आहे का? I: a = 3. II: b = 0.
Aकेवळ II पुरेसे आहे
Bदोन्ही मिळूनही पुरेसे नाही
Cदोन्ही एकत्र आवश्यक आहेत
Dकेवळ I पुरेसे आहे
Answer & Solution
Correct answer: D. केवळ I पुरेसे आहे
सहगुणक a शून्येतर असल्याने, b चे मूल्य काहीही असले तरी समीकरणाचे एकुलते एक मूळ -b/a असते.
