किस मान पर ((n+2)x+3n-1) का शून्यक (1) होगा?
For which value will the zero of ((n+2)x+3n-1) be (1)?
Explanation opens after your attempt
A. \(n=-\frac{1}{4}\)
Concept
If the zero is (1), then (n+2+3n-1=0). Thus (4n+1=0) and \(n=-\frac{1}{4}\).
Why this answer is correct
The correct answer is A. \(n=-\frac{1}{4}\). If the zero is (1), then (n+2+3n-1=0). Thus (4n+1=0) and \(n=-\frac{1}{4}\).
Exam Tip
शून्यक (1) होने पर (n+2+3n-1=0) होगा। इससे (4n+1=0) और \(n=-\frac{1}{4}\) मिलता है।
