Which polynomial has −1 and 4 as its zeroes?किस बहुपद के शून्यक −1 और 4 हैं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(x^2-3x-4\)\(x^2-3x-4\)
A monic polynomial with zeroes −1 and 4 is \((x+1)(x-4)\). Expanding gives \(x^2-3x-4\), so option A is correct.शून्यक −1 और 4 वाला एकात्मक बहुपद \((x+1)(x-4)\) होता है। इसे विस्तार देने पर \(x^2-3x-4\) मिलता है, इसलिए विकल्प A सही है।
