Easy Mathematics Quadratic Equations Class 10 Level 32

यदि (0) समीकरण \(2x^2+bx+c=0\) का मूल है तो (c) का मान कैसा होगा?

If (0) is a root of \(2x^2+bx+c=0\), what must be the value of (c)?

Explanation opens after your attempt
Correct Answer

A. (c=0)

Step 1

Concept

Putting (x=0) must give (c=0). Therefore the constant term is zero for a zero root.

Step 2

Why this answer is correct

The correct answer is A. (c=0). Putting (x=0) must give (c=0). Therefore the constant term is zero for a zero root.

Step 3

Exam Tip

(x=0) रखने पर (c=0) मिलना चाहिए। इसलिए शून्य मूल के लिए अचर पद शून्य होता है।
