Explanation opens after your attempt
Correct Answer
A. जड़ों का अंतर हमेशा (6) हैThe difference of roots is always (6)
Concept
The equation can be written as ((x-p)2-9=0). The roots are (p+3) and (p-3), so the difference is (6).
Why this answer is correct
The correct answer is A. जड़ों का अंतर हमेशा (6) है / The difference of roots is always (6). The equation can be written as ((x-p)2-9=0). The roots are (p+3) and (p-3), so the difference is (6).
Exam Tip
समीकरण को ((x-p)2-9=0) लिखा जा सकता है। जड़ें (p+3) और (p-3) हैं, इसलिए अंतर (6) है।
