In which of the following terms is the coefficient of the variable negative?निम्नलिखित में से किस पद में चर का गुणांक ऋणात्मक है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(-3y\)\(-3y\)
In the term \(-3y\), the coefficient of \(y\) is \(-3\), which is negative. The coefficients of \(5x\), \(z\), and \(\frac{1}{2}p\) are \(5\), \(1\), and \(\frac{1}{2}\), respectively, and all are positive. Exam tip: When no number is written before a variable, its coefficient is \(1\).पद \(-3y\) में चर \(y\) का गुणांक \(-3\) है, जो ऋणात्मक है। \(5x\), \(z\) और \(\frac{1}{2}p\) के गुणांक क्रमशः \(5\), \(1\) और \(\frac{1}{2}\) हैं, जो धनात्मक हैं। परीक्षा टिप: यदि चर के आगे कोई संख्या न हो, तो उसका गुणांक \(1\) होता है।
