Correct Answer

A. (4kx)

Step 1

Concept

The difference of expansions is (x-2+2kx+k-2-\(x^2-2kx+k^2\)=4kx). In exams, cancel equal square terms.

Step 2

Why this answer is correct

The correct answer is A. (4kx). The difference of expansions is (x-2+2kx+k-2-\(x^2-2kx+k^2\)=4kx). In exams, cancel equal square terms.

Step 3

Exam Tip

विस्तारों का अंतर (x-2+2kx+k-2-\(x^2-2kx+k^2\)=4kx) है। परीक्षा में समान वर्ग पद काटें।
