यदि (x-2-2(m+1)x+\(m^2+2m+1\)=0) के मूल बराबर हैं तो (m) के लिए क्या सही है?
If roots of (x-2-2(m+1)x+\(m^2+2m+1\)=0) are equal, what is true for (m)?
Explanation opens after your attempt
Correct Answer
A. हर वास्तविक (m)Every real (m)
Concept
The constant term is ((m+1)2), and the equation becomes ((x-(m+1))2=0). Hence roots are equal for every real (m).
Why this answer is correct
The correct answer is A. हर वास्तविक (m) / Every real (m). The constant term is ((m+1)2), and the equation becomes ((x-(m+1))2=0). Hence roots are equal for every real (m).
Exam Tip
अचर पद ((m+1)2) है और समीकरण ((x-(m+1))2=0) बनता है। इसलिए हर वास्तविक (m) के लिए मूल बराबर हैं।
