Question 1/5
Expert Mathematics
Quadratic Equations Introduction to Quadratic Equations Class 10 Level 30
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
Step 1
Concept
The equation is ((x-a)2-49=0), so the roots are (a+7) and (a-7). Their difference is (14).
Step 2
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).
Step 3
Exam Tip
समीकरण ((x-a)2-49=0) है, इसलिए मूल (a+7) और (a-7) हैं। उनका अंतर (14) है।
