If \(p(x)=3x-12\), what is its zero?यदि \(p(x)=3x-12\) है, तो इसका शून्यक क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 44
A zero of a polynomial is the value of \(x\) for which \(p(x)=0\). Thus, \(3x-12=0\), so \(3x=12\) and \(x=4\). Option D is incorrect because the constant term must be divided by the coefficient of \(x\). Exam tip: the zero of a linear polynomial \(ax+b\) is \(-\frac{b}{a}\).बहुपद का शून्यक वह मान होता है जिसके लिए \(p(x)=0\) हो। इसलिए \(3x-12=0\), अर्थात \(3x=12\) और \(x=4\)। विकल्प D में केवल 12 लिया गया है, जबकि 3 से भाग देना आवश्यक है। परीक्षा-युक्ति: रैखिक बहुपद \(ax+b\) का शून्यक \(-\frac{b}{a}\) होता है।
