Correct Answer

D. ((x+y-2z+2)(x+y+2z+2))

Step 1

Concept

Writing it as ((x+y)2+4(x+y)-4z-2) does not directly factor as option (D). Verify by expansion carefully.

Step 2

Why this answer is correct

The correct answer is D. ((x+y-2z+2)(x+y+2z+2)). Writing it as ((x+y)2+4(x+y)-4z-2) does not directly factor as option (D). Verify by expansion carefully.

Step 3

Exam Tip

इसे ((x+y)2+4(x+y)-4z-2) लिखने से तुरंत नहीं टूटता, पर ((x+y+2)2-(2z)2-4) नहीं है। सही जाँच विस्तार से करें।
