Correct Answer

A. (1)

Step 1

Concept

(\(\alpha-\beta\)2=\(\alpha+\beta\)2-4\alpha\beta=25-24=1). This identity avoids finding the zeroes separately.

Step 2

Why this answer is correct

The correct answer is A. (1). (\(\alpha-\beta\)2=\(\alpha+\beta\)2-4\alpha\beta=25-24=1). This identity avoids finding the zeroes separately.

Step 3

Exam Tip

(\(\alpha-\beta\)2=\(\alpha+\beta\)2-4\alpha\beta=25-24=1)। इस पहचान से शून्यक निकाले बिना उत्तर मिल जाता है।
