Concept

The square root is in the denominator, so ((x+2)(5-x)>0) is required. In exams do not include equality for a denominator radical.

Step 2

Why this answer is correct

The correct answer is A. ((-2,5)). The square root is in the denominator, so ((x+2)(5-x)>0) is required. In exams do not include equality for a denominator radical.

Exam Tip

हर में वर्गमूल है इसलिए ((x+2)(5-x)>0) चाहिए। परीक्षा में denominator radical के लिए बराबरी शामिल न करें।
