Question Hard Mathematics Quadratic Equations Roots of a Quadratic Equation Class 10 Level 32

यदि समीकरण (x-2-4x+(m+4)=0) के वास्तविक मूल नहीं हैं तो (m) के लिए कौन सी शर्त सही है?

If (x-2-4x+(m+4)=0) has no real roots, which condition on (m) is correct?

Explanation opens after your attempt
Correct Answer

A. (m>0)

Step 1

Concept

For no real roots (D<0) is required. From (16-4(m+4)<0), we get (m>0).

Step 2

Why this answer is correct

The correct answer is A. (m>0). For no real roots (D<0) is required. From (16-4(m+4)<0), we get (m>0).

Step 3

Exam Tip

वास्तविक मूल नहीं होने के लिए (D<0) चाहिए। (16-4(m+4)<0) से (m>0) मिलता है।

Question Medium Mathematics Quadratic Equations Roots of a Quadratic Equation Class 10 Level 33

समीकरण \(x^2+6x+k=0\) के वास्तविक मूल होने के लिए (k) के बारे में कौन सी शर्त सही है?

For \(x^2+6x+k=0\) to have real roots, which condition on (k) is correct?

Explanation opens after your attempt
Correct Answer

A. \(k\le9\)

Step 1

Concept

For real roots \(D\ge0\) is required. From \(36-4k\ge0\), we get \(k\le9\).

Step 2

Why this answer is correct

The correct answer is A. \(k\le9\). For real roots \(D\ge0\) is required. From \(36-4k\ge0\), we get \(k\le9\).

Step 3

Exam Tip

वास्तविक मूलों के लिए \(D\ge0\) चाहिए। \(36-4k\ge0\) से \(k\le9\) मिलता है।
