Aarav claims that the zero of the linear polynomial \(4x-9\) is \(-\frac{9}{4}\). What is the correct zero after fixing his error?आरव का कहना है कि रेखीय बहुपद \(4x-9\) का शून्यक \(-\frac{9}{4}\) है। उसकी त्रुटि सुधारने पर सही शून्यक क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(\frac{9}{4}\)\(\frac{9}{4}\)
For a zero, set \(4x-9=0\). Then \(4x=9\), so \(x=\frac{9}{4}\). The value \(-\frac{9}{4}\) comes from a sign error. In exams, substitute the answer to verify it.शून्यक पाने के लिए \(4x-9=0\) रखें। इससे \(4x=9\), अतः \(x=\frac{9}{4}\) मिलता है। \(-\frac{9}{4}\) में चिन्ह की गलती है। परीक्षा में मान रखकर जाँचें।
