किस मान के लिए \(x^2-4x+m\) में (x=1) शून्य होगा?

For what value of (m) will (x=1) be a zero of \(x^2-4x+m\)?

Explanation opens after your attempt
Correct Answer

C. (3)

Step 1

Concept

(1-4+m=0), so (m=3). When a zero is given, set the polynomial value equal to (0).

Step 2

Why this answer is correct

The correct answer is C. (3). (1-4+m=0), so (m=3). When a zero is given, set the polynomial value equal to (0).

Step 3

Exam Tip

(1-4+m=0), इसलिए (m=3)। शून्य मिलने पर बहुपद का मान (0) रखें।
