Which polynomial in (x) has four terms?कौन-सा बहुपद (x) में चार पदों वाला है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(x^3+x^2+x+1\)\(x^3+x^2+x+1\)
The terms of \(x^3+x^2+x+1\) are \(x^3\), \(x^2\), \(x\), and \(1\), so it has four terms. \(x^2+x+1\) has three terms, whereas \(x^4-1\) has only two terms. Exam tip: Count terms by separating them at plus or minus signs.\(x^3+x^2+x+1\) के पद \(x^3\), \(x^2\), \(x\) और \(1\) हैं, इसलिए इसमें चार पद हैं। \(x^2+x+1\) में तीन पद हैं, जबकि \(x^4-1\) में केवल दो पद हैं। परीक्षा टिप: बहुपद में पदों को जोड़ या घटाव के चिह्नों से अलग करके गिनें।
