यदि \(x^2-2ax+a^2-49=0\) है, तो मूलों का अंतर क्या होगा?
If \(x^2-2ax+a^2-49=0\), what will be the difference of the roots?
Explanation opens after your attempt
Correct Answer
A. (14)
Concept
The equation is ((x-a)2-49=0), so the roots are (a+7) and (a-7). Their difference is (14).
Why this answer is correct
The correct answer is A. (14). The equation is ((x-a)2-49=0), so the roots are (a+7) and (a-7). Their difference is (14).
Exam Tip
समीकरण ((x-a)2-49=0) है, इसलिए मूल (a+7) और (a-7) हैं। उनका अंतर (14) है।
