Correct Answer
A. \(x^2-8x=0\)
Concept
In \(x^2-8x=0\), (x) is a common factor and (x=0) can be a root. In exams, write (x(x-8)=0) in such cases.
Why this answer is correct
The correct answer is A. \(x^2-8x=0\). In \(x^2-8x=0\), (x) is a common factor and (x=0) can be a root. In exams, write (x(x-8)=0) in such cases.
Exam Tip
\(x^2-8x=0\) में (x) सामान्य गुणनखंड है और (x=0) मूल हो सकता है। परीक्षा में ऐसे मामलों में (x(x-8)=0) लिखें।
