Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x<-1) or (x>2)(x<-1) या (x>2)
The fraction is positive when numerator and denominator have the same sign. In exams (x=-1) makes the denominator zero, so it is excluded.भिन्न धनात्मक है जब अंश और हर समान चिह्न के हों। परीक्षा में (x=-1) हर को शून्य करता है, इसलिए शामिल नहीं होगा।
