Expert Mathematics Quadratic Equations Class 10 Level 28

किस समीकरण का विवेचक (-23) है?

Which equation has discriminant (-23)?

Explanation opens after your attempt
Correct Answer

A. \(x^2+x+6=0\)

Step 1

Concept

For \(x^2+x+6=0\), \(D=1^2-4\cdot1\cdot6=-23\). Subtract the full (4ac) in the discriminant.

Step 2

Why this answer is correct

The correct answer is A. \(x^2+x+6=0\). For \(x^2+x+6=0\), \(D=1^2-4\cdot1\cdot6=-23\). Subtract the full (4ac) in the discriminant.

Step 3

Exam Tip

\(x^2+x+6=0\) के लिए \(D=1^2-4\cdot1\cdot6=-23\) है। विवेचक में (4ac) पूरा घटाएं।
