Easy Mathematics Quadratic Equations Class 10 Level 37

समीकरण \(x^2+6x+k=0\) के समान वास्तविक मूल होने के लिए (k) का मान क्या होगा?

For \(x^2+6x+k=0\) to have equal real roots, what should be the value of (k)?

Explanation opens after your attempt
Correct Answer

A. (9)

Step 1

Concept

For equal roots (D=0), so \(6^2-4k=0\) gives (k=9). Use (D=0) in such questions.

Step 2

Why this answer is correct

The correct answer is A. (9). For equal roots (D=0), so \(6^2-4k=0\) gives (k=9). Use (D=0) in such questions.

Step 3

Exam Tip

समान मूलों के लिए (D=0), इसलिए \(6^2-4k=0\) से (k=9)। ऐसे प्रश्न में (D=0) लगाएं।
