\(x^2-8x+15=0\) 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))

Step 1

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.

Step 2

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.

Step 3

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।
