यदि (\(\alpha+3\)x-2-2\alpha x+\(\alpha-2\)=0) में \(\alpha\neq-3\) हो, तो वास्तविक मूलों के लिए \(\alpha\) की शर्त क्या है?
If \(\alpha\neq-3\) in (\(\alpha+3\)x-2-2\alpha x+\(\alpha-2\)=0), what is the condition on \(\alpha\) for real roots?
Explanation opens after your attempt
A. \(\alpha\leq3\) और \(\alpha\neq-3\)\(\alpha\leq3\) and \(\alpha\neq-3\)
Concept
Here (D=4\alpha-2-4\(\alpha+3\)\(\alpha-2\)=24-4\alpha). For real roots \(\alpha\leq3\), and for a quadratic \(\alpha\neq-3\).
Why this answer is correct
The correct answer is A. \(\alpha\leq3\) और \(\alpha\neq-3\) / \(\alpha\leq3\) and \(\alpha\neq-3\). Here (D=4\alpha-2-4\(\alpha+3\)\(\alpha-2\)=24-4\alpha). For real roots \(\alpha\leq3\), and for a quadratic \(\alpha\neq-3\).
Exam Tip
यहाँ (D=4\alpha-2-4\(\alpha+3\)\(\alpha-2\)=24-4\alpha) है। वास्तविक मूलों के लिए \(\alpha\leq3\) और द्विघात के लिए \(\alpha\neq-3\)।
