यदि (p(x)=(x+a)3(x-b)2), जहाँ \(a\neq -b\), तो अलग शून्यक कौन से हैं?
If (p(x)=(x+a)3(x-b)2), where \(a\neq -b\), what are the distinct zeroes?
Explanation opens after your attempt
A. (-a) और (b)(-a) and (b)
Concept
From (x+a=0) we get (-a), and from (x-b=0) we get (b). Tip: do not count repetition among distinct zeroes.
Why this answer is correct
The correct answer is A. (-a) और (b) / (-a) and (b). From (x+a=0) we get (-a), and from (x-b=0) we get (b). Tip: do not count repetition among distinct zeroes.
Exam Tip
(x+a=0) से (-a) और (x-b=0) से (b) मिलता है। टिप: अलग शून्यकों में दोहराव न गिनें।
