Download Solution PDFप्रयुक्त अवधारणा:
यदि एक द्विघात समीकरण (ax 2 + bx + c = 0) है।
तब, मूलों का योग = -b/a
जहाँ b = x का गुणांक
a = x2का गुणांक
गणना:
यहाँ, \(\sqrt2\)x2 - 2\(\sqrt5\)x + \(\sqrt3\) = 0
अब, समीकरण को \(\sqrt2\) से विभाजित करें
⇒ x2 - \(\sqrt2\) × \(\sqrt5\) x + \(\sqrt3\over\sqrt2\) = 0
अब, यह ax 2 + bx + c = 0 के रूप में है
जहां, a= 1 , b = -\(\sqrt{10}\) , c = \(\sqrt3\over \sqrt2\)
अब, जैसा कि हम जानते हैं कि मूलों का योग = -b/a
⇒ -b/a = - ( -\(\sqrt{10}\) ) = \(\sqrt{10}\)
अत: मूलों का अभीष्ट योग \(\sqrt{10}\) है।
