\(x^2-y^2+4x+4\) का गुणनखंडन क्या होगा?
What will be the factorisation of \(x^2-y^2+4x+4\)?
Explanation opens after your attempt
A. ((x+2-y)(x+2+y))
Concept
(x-2+4x+4=(x+2)2). Therefore it becomes ((x+2)2-y-2).
Why this answer is correct
The correct answer is A. ((x+2-y)(x+2+y)). (x-2+4x+4=(x+2)2). Therefore it becomes ((x+2)2-y-2).
Exam Tip
(x-2+4x+4=(x+2)2) है। इसलिए यह ((x+2)2-y-2) बनता है।
