Correct Answer

A. \(n=-\frac{1}{4}\)

Step 1

Concept

If the zero is (1), then (n+2+3n-1=0). Thus (4n+1=0) and \(n=-\frac{1}{4}\).

Step 2

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 \(n=-\frac{1}{4}\).

Step 3

Exam Tip

शून्यक (1) होने पर (n+2+3n-1=0) होगा। इससे (4n+1=0) और \(n=-\frac{1}{4}\) मिलता है।
