समीकरण (3x-2-2(2a+1)x+\(a^2+a+1\)=0) के वास्तविक मूलों के लिए (a) पर क्या शर्त है?

What condition on (a) is needed for real roots of (3x-2-2(2a+1)x+\(a^2+a+1\)=0)?

Explanation opens after your attempt
Correct Answer

A. \(a^2+a-2\ge0\)

Step 1

Concept

Here (D=4(2a+1)2-12\(a^2+a+1\)=4\(a^2+a-2\)). For real roots, it must be (0) or more.

Step 2

Why this answer is correct

The correct answer is A. \(a^2+a-2\ge0\). Here (D=4(2a+1)2-12\(a^2+a+1\)=4\(a^2+a-2\)). For real roots, it must be (0) or more.

Step 3

Exam Tip

यहाँ (D=4(2a+1)2-12\(a^2+a+1\)=4\(a^2+a-2\)) है। वास्तविक मूलों के लिए यह (0) या अधिक होना चाहिए।
