Detailed Solution
Download Solution PDF2x2 + 4x = 30 या समीकरणाचे मूळ
2x 2 + 4x - 30 = 0
2 ने विभाजित केले
x 2 + 2x - 15 = 0
x 2 + 5x - 3x - 15 = 0
x (x + 5) - 3 (x + 5) = 0
(x + 5) (x - 3) = 0
घेऊन,
(x + 5) = 0
x = (-5)
घेऊन,
(x - 3) = 0
x = 3
तर, 2x 2 + 4x = 30 या समीकरणाची मुळे (-5) आणि 3 आहेत.
टीपः उत्तर पटकन शोधण्यासाठी आपण पर्यायांची मूल्ये थेट समीकरणात ठेवू शकतो आणि मूल्ये समीकरण पूर्ण करतात की नाही ते तपासू शकतो.
