\(x^2+10x+25-y^2\) का सही गुणनखंडन कौन सा है?
Which is the correct factorisation of \(x^2+10x+25-y^2\)?
Explanation opens after your attempt
D. ((x+5-y)(x+5+y))
Concept
First identify (x-2+10x+25=(x+5)2). Then difference of squares gives ((x+5-y)(x+5+y)).
Why this answer is correct
The correct answer is D. ((x+5-y)(x+5+y)). First identify (x-2+10x+25=(x+5)2). Then difference of squares gives ((x+5-y)(x+5+y)).
Exam Tip
पहले (x-2+10x+25=(x+5)2) पहचानें। फिर वर्गों के अंतर से ((x+5-y)(x+5+y)) मिलेगा।
