Medium Mathematics Quadratic Equations Class 10 Level 31

समीकरण \(2x^2-4x+2=0\) का डिस्क्रिमिनेंट (D) क्या है?

What is the discriminant (D) of \(2x^2-4x+2=0\)?

Explanation opens after your attempt
Correct Answer

A. (0)

Step 1

Concept

Here \(D=b^2-4ac=16-16=0\). Therefore the two real roots will be equal.

Step 2

Why this answer is correct

The correct answer is A. (0). Here \(D=b^2-4ac=16-16=0\). Therefore the two real roots will be equal.

Step 3

Exam Tip

यहां \(D=b^2-4ac=16-16=0\) है। इसलिए दोनों वास्तविक मूल बराबर होंगे।
