\(x^2-5x=0\) में (x=0) मूल क्यों है?
Why is (x=0) a root of \(x^2-5x=0\)?
Explanation opens after your attempt
Correct Answer
A. क्योंकि (x(x-5)=0)Because (x(x-5)=0)
Concept
(x-2-5x=x(x-5)), so zero product rule gives (x=0). In exams, do not lose this root by dividing by the variable.
Why this answer is correct
The correct answer is A. क्योंकि (x(x-5)=0) / Because (x(x-5)=0). (x-2-5x=x(x-5)), so zero product rule gives (x=0). In exams, do not lose this root by dividing by the variable.
Exam Tip
(x-2-5x=x(x-5)), इसलिए शून्य गुणनफल नियम से (x=0) मिलता है। परीक्षा में चर से भाग देकर यह मूल न खोएं।
