\(x^2-8x+15=0\) के गुणनखंड कौनसे होंगे?
What will be the factors of \(x^2-8x+15=0\)?
Explanation opens after your attempt
Correct Answer
A. ((x-3)(x-5))
Concept
(3+5=8) and \(3\times5=15\), so with signs we get ((x-3)(x-5)). In exams, for a negative middle term, look for both negative factors.
Why this answer is correct
The correct answer is A. ((x-3)(x-5)). (3+5=8) and \(3\times5=15\), so with signs we get ((x-3)(x-5)). In exams, for a negative middle term, look for both negative factors.
Exam Tip
(3+5=8) और \(3\times5=15\), इसलिए संकेतों के साथ ((x-3)(x-5)) मिलता है। परीक्षा में ऋणात्मक मध्य पद के लिए दोनों ऋणात्मक गुणनखंड देखें।
