\(x^2-3x=0\) में (x=0) क्यों एक मूल है?

Why is (x=0) a root of \(x^2-3x=0\)?

Explanation opens after your attempt
Correct Answer

A. क्योंकि (x(x-3)=0)Because (x(x-3)=0)

Step 1

Concept

(x-2-3x=x(x-3)), so zero product rule gives (x=0). In exams, do not lose (x=0) by dividing by (x).

Step 2

Why this answer is correct

The correct answer is A. क्योंकि (x(x-3)=0) / Because (x(x-3)=0). (x-2-3x=x(x-3)), so zero product rule gives (x=0). In exams, do not lose (x=0) by dividing by (x).

Step 3

Exam Tip

(x-2-3x=x(x-3)), इसलिए शून्य गुणनफल नियम से (x=0) मिलता है। परीक्षा में (x) से भाग देकर (x=0) न खोएं।
