Which option gives the correct solution of (\frac{x-4}{x+2}<0)?किस विकल्प में (\frac{x-4}{x+2}<0) का हल सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-2<x<4)(-2<x<4)
The fraction is negative when numerator and denominator have opposite signs. In exams (x=-2) makes the denominator zero and (x=4) gives (0), so both are excluded.भिन्न ऋणात्मक तब होता है जब अंश और हर विपरीत चिह्न के हों। परीक्षा में (x=-2) हर को शून्य करता है और (x=4) पर मान (0) है, इसलिए दोनों शामिल नहीं हैं।
