Explanation opens after your attempt
Correct Answer

D. ((x+5-y)(x+5+y))

Step 1

Concept

First identify (x-2+10x+25=(x+5)2). Then difference of squares gives ((x+5-y)(x+5+y)).

Step 2

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)).

Step 3

Exam Tip

पहले (x-2+10x+25=(x+5)2) पहचानें। फिर वर्गों के अंतर से ((x+5-y)(x+5+y)) मिलेगा।
