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