\(16x^2-25=0\) के मूल क्या हैं?
What are the roots of \(16x^2-25=0\)?
Explanation opens after your attempt
Correct Answer
A. \(x=\frac{5}{4},-\frac{5}{4}\)
Concept
((4x-5)(4x+5)=0), so \(x=\frac{5}{4}\) or \(x=-\frac{5}{4}\). In exams, solve linear factors carefully.
Why this answer is correct
The correct answer is A. \(x=\frac{5}{4},-\frac{5}{4}\). ((4x-5)(4x+5)=0), so \(x=\frac{5}{4}\) or \(x=-\frac{5}{4}\). In exams, solve linear factors carefully.
Exam Tip
((4x-5)(4x+5)=0), इसलिए \(x=\frac{5}{4}\) या \(x=-\frac{5}{4}\) है। परीक्षा में रैखिक गुणनखंड सावधानी से हल करें।
