द्विघात समीकरण के वास्तविक और समान मूल होते हैं
गणना:
माना मूल m और n हैं
प्रश्न के अनुसार,
m = \(\frac{3}{5}\), और n = \(\frac{3}{5}\)
अब, मूलों का योग = m + n = \(\frac{3}{5}\) + \(\frac{3}{5}\)
जड़ों का योग = \(6\over5\)मूलों का गुणनफल = mn = \(\frac{3}{5}\) * \(\frac{3}{5}\)
मूलों का गुणनफल = \(9\over25\)
अब, मानों को द्विघात समीकरण सूत्र में रखें,
x2 - (m + n)x + mn = 0
x2 - \(6\over5\)x + \(9\over25\) = 0
हल करने पर हम पाते हैं,
25x2 - 30x + 9 = 0
25x2 - 30x + 9 = 0
अतः द्विघात समीकरण '25x2 - 30x + 9 = 0' होगा।
