यदि \(x^2-2ax+a^2-16=0\) है, तो मूलों का अंतर क्या होगा?
If \(x^2-2ax+a^2-16=0\), what will be the difference of the roots?
Explanation opens after your attempt
A. (8)
Concept
The equation is ((x-a)2-16=0), so the roots are (a+4) and (a-4). Their difference is (8).
Why this answer is correct
The correct answer is A. (8). The equation is ((x-a)2-16=0), so the roots are (a+4) and (a-4). Their difference is (8).
Exam Tip
समीकरण ((x-a)2-16=0) है, इसलिए मूल (a+4) और (a-4) हैं। उनका अंतर (8) है।
