Which condition is correct for real roots in (2x^2+(2k+1)x+5=0)?समीकरण (2x^2+(2k+1)x+5=0) में वास्तविक मूलों के लिए सही शर्त कौन सी है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (k\leq\frac{-1-2\sqrt{10}}{2}) or (k\geq\frac{-1+2\sqrt{10}}{2})(k\leq\frac{-1-2\sqrt{10}}{2}) या (k\geq\frac{-1+2\sqrt{10}}{2})
For real roots, ((2k+1)^2-40\geq0) is needed. Hence (2k+1\leq-2\sqrt{10}) or (2k+1\geq2\sqrt{10}).वास्तविक मूलों के लिए ((2k+1)^2-40\geq0) चाहिए। इसलिए (2k+1\leq-2\sqrt{10}) या (2k+1\geq2\sqrt{10})।
