Medium Mathematics Quadratic Equations Class 10 Level 33

यदि (x=0) समीकरण \(2x^2+mx+n=0\) का मूल है तो (n) का मान क्या होगा?

If (x=0) is a root of \(2x^2+mx+n=0\), what will be the value of (n)?

Explanation opens after your attempt
Correct Answer

A. (0)

Step 1

Concept

Putting (x=0) leaves only (n). Therefore (n=0) must hold.

Step 2

Why this answer is correct

The correct answer is A. (0). Putting (x=0) leaves only (n). Therefore (n=0) must hold.

Step 3

Exam Tip

(x=0) रखने पर केवल (n) बचता है। इसलिए (n=0) होना चाहिए।
