यदि किसी परवलय का (x)-अक्ष से कोई साझा बिंदु नहीं है, तो द्विघात बहुपद के वास्तविक शून्यक कितने होंगे?
If a parabola has no common point with the (x)-axis, how many real zeroes does the quadratic polynomial have?
Explanation opens after your attempt
A. (0)
Concept
Real zeroes are found only when the graph meets the (x)-axis. With no common point, there are (0) real zeroes.
Why this answer is correct
The correct answer is A. (0). Real zeroes are found only when the graph meets the (x)-axis. With no common point, there are (0) real zeroes.
Exam Tip
वास्तविक शून्यक तभी मिलते हैं जब ग्राफ (x)-अक्ष से मिले। साझा बिंदु न होने पर वास्तविक शून्यक (0) होंगे।
