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