For which (r) will (rx^2-5x+r=0) have two distinct real roots?किस (r) के लिए (rx^2-5x+r=0) के दो भिन्न वास्तविक मूल होंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (r^2<\frac{25}{4}) and (r\neq0)(r^2<\frac{25}{4}) और (r\neq0)
For two distinct real roots, (D>0), so (25-4r^2>0). Also (r\neq0) is needed because the equation must remain quadratic.दो भिन्न वास्तविक मूलों के लिए (D>0), इसलिए (25-4r^2>0)। साथ में (r\neq0) चाहिए क्योंकि समीकरण द्विघात होना चाहिए।
