A. (1)
Concept
(\alpha\beta=25-\(2\sqrt{6}\)2=25-24=1). In exams square terms correctly in conjugate multiplication.
Why this answer is correct
The correct answer is A. (1). (\alpha\beta=25-\(2\sqrt{6}\)2=25-24=1). In exams square terms correctly in conjugate multiplication.
Exam Tip
(\alpha\beta=25-\(2\sqrt{6}\)2=25-24=1) है। परीक्षा में संयुग्मी गुणन में वर्ग सही करें।
