Easy Mathematics Quadratic Equations Class 10 Level 33

यदि (0) समीकरण \(5x^2+kx+c=0\) का मूल है तो कौन सा पद शून्य होना चाहिए?

If (0) is a root of \(5x^2+kx+c=0\), which term must be zero?

Explanation opens after your attempt
Correct Answer

A. अचर पद (c)Constant term (c)

Step 1

Concept

Putting (x=0) leaves only (c). Therefore for a zero root, (c=0) must hold.

Step 2

Why this answer is correct

The correct answer is A. अचर पद (c) / Constant term (c). Putting (x=0) leaves only (c). Therefore for a zero root, (c=0) must hold.

Step 3

Exam Tip

(x=0) रखने पर केवल (c) बचता है। इसलिए शून्य मूल के लिए (c=0) होना चाहिए।
