यदि (2x-2-2\(\mu+3\)x+\mu-2+6\mu+5=0) के मूल वास्तविक और भिन्न हैं, तो \(\mu\) पर क्या शर्त है?
If (2x-2-2\(\mu+3\)x+\mu-2+6\mu+5=0) has real and distinct roots, what is the condition on \(\mu\)?
Explanation opens after your attempt
A. सभी वास्तविक \(\mu\)All real \(\mu\)
Concept
Here (D=4\(\mu+3\)2-8\(\mu^2+6\mu+5\)=-4\(\mu^2+6\mu+1\)). It is not always positive, so all \(\mu\) is not correct.
Why this answer is correct
The correct answer is A. सभी वास्तविक \(\mu\) / All real \(\mu\). Here (D=4\(\mu+3\)2-8\(\mu^2+6\mu+5\)=-4\(\mu^2+6\mu+1\)). It is not always positive, so all \(\mu\) is not correct.
Exam Tip
यहाँ (D=4\(\mu+3\)2-8\(\mu^2+6\mu+5\)=-4\(\mu^2+6\mu+1\)) है। यह हमेशा धनात्मक नहीं है, इसलिए सभी \(\mu\) सही नहीं है।
