वापरलेली संकल्पना:

जर द्विघात समीकरण (ax 2 + bx + c = 0)

नंतर, मुळांची बेरीज = -b/a

जेथे b = x चा गुणांक

a = x 2 चा गुणांक

गणना:

येथे, आपल्याकडे x 2 - 2 x + = 0 आहे.

आता समीकरणाला ने विभाजित करा.

⇒ x 2 - x x + = 0

आता, हे ax 2 + bx + c = 0 च्या रूपात आहे

कुठे , a= 1 , b = - , c =

आता, आपल्याला माहित आहे की मुळांची बेरीज = -b/a

⇒ -b/a = - ( - \(\sqrt{10}\) ) =

म्हणून, मुळांची आवश्यक बेरीज आहे .
