Which option has coefficient of (x) equal to (1)?किस विकल्प में (x) का गुणांक (1) है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: x - 5x - 5
Option A is x - 5, which can be written as 1x - 5. Therefore, the coefficient of x is 1. In option C, the minus sign before x means that its coefficient is -1, not 1. Exam tip: When no number is written before x, its coefficient is usually taken as 1.विकल्प A में व्यंजक x - 5 है, जिसे 1x - 5 लिखा जा सकता है। अतः x का गुणांक 1 है। विकल्प C में x के पहले ऋण चिह्न है, इसलिए उसका गुणांक -1 है, 1 नहीं। परीक्षा टिप: किसी पद में x के आगे कोई संख्या न लिखी हो, तो उसका गुणांक सामान्यतः 1 माना जाता है।
