Hard Mathematics Quadratic Equations Class 10 Level 30

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
Correct Answer

A. (8)

Step 1

Concept

The equation is ((x-a)2-16=0), so the roots are (a+4) and (a-4). Their difference is (8).

Step 2

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).

Step 3

Exam Tip

समीकरण ((x-a)2-16=0) है, इसलिए मूल (a+4) और (a-4) हैं। उनका अंतर (8) है।
