Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
द्विघात समीकरण ax2 + bx + c = 0 के लिए
मूलों का योगफल = -b/a
और मूलों का गुणनफल = c/a
गणना:
यदि मूलों का योगफल = मूलों का गुणनफल
⇒ \(\frac{-b}{a}=\frac ca\)
⇒ -b = c
अतः, -b = c और a ≠ 0 के साथ अपरिमित रूप से कई द्विघात समीकरण हो सकते हैं
∴ सही विकल्प (4) है।
