यदि किसी घन बहुपद का ग्राफ (x)-अक्ष को केवल एक बार काटता है, तो वास्तविक शून्यकों की संख्या क्या मानी जाएगी?
If the graph of a cubic polynomial cuts the (x)-axis only once, what is the number of real zeroes?
Explanation opens after your attempt
Correct Answer
A. एकOne
Concept
There is only one intersection, so there is one real zero. Tip: a cubic can have at most three real zeroes, not necessarily three.
Why this answer is correct
The correct answer is A. एक / One. There is only one intersection, so there is one real zero. Tip: a cubic can have at most three real zeroes, not necessarily three.
Exam Tip
कटान केवल एक है इसलिए एक वास्तविक शून्यक है। टिप: घन बहुपद में अधिकतम तीन वास्तविक शून्यक हो सकते हैं, जरूरी नहीं कि तीन हों।
