\(x^2+xy+3x+3y\) में समूह बनाकर सही गुणनखंडन क्या है?
What is the correct factorisation of \(x^2+xy+3x+3y\) by grouping?
Explanation opens after your attempt
B. ((x+3)(x+y))
Concept
Grouping gives (x(x+y)+3(x+y)). Taking common ((x+y)) gives ((x+3)(x+y)).
Why this answer is correct
The correct answer is B. ((x+3)(x+y)). Grouping gives (x(x+y)+3(x+y)). Taking common ((x+y)) gives ((x+3)(x+y)).
Exam Tip
समूह करने पर (x(x+y)+3(x+y)) मिलता है। समान ((x+y)) निकालने पर ((x+3)(x+y)) है।
