\(x^2-2tx+t^2-49=0\) की जड़ों का धनात्मक अंतर क्या है?
What is the positive difference between the roots of \(x^2-2tx+t^2-49=0\)?
Explanation opens after your attempt
Correct Answer
B. (14)
Concept
The equation is ((x-t)2-49=0). The roots are (t+7) and (t-7), so the positive difference is (14).
Why this answer is correct
The correct answer is B. (14). The equation is ((x-t)2-49=0). The roots are (t+7) and (t-7), so the positive difference is (14).
Exam Tip
समीकरण ((x-t)2-49=0) है। जड़ें (t+7) और (t-7) हैं, इसलिए धनात्मक अंतर (14) है।
