Question 1/7 Expert Mathematics Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 23

परवलय (x)-अक्ष को दो बिंदुओं पर काटता है और (y)-अक्ष को ((0,25)) पर काटता है। वास्तविक शून्यकों की संख्या क्या है?

A parabola cuts the (x)-axis at two points and cuts the (y)-axis at ((0,25)). What is the number of real zeroes?

Explanation opens after your attempt
Correct Answer

B. दोTwo

Step 1

Concept

Real zeroes are counted from (x)-axis intersections, not from the (y)-axis intercept. Tip: ((0,25)) does not show a zero.

Step 2

Why this answer is correct

The correct answer is B. दो / Two. Real zeroes are counted from (x)-axis intersections, not from the (y)-axis intercept. Tip: ((0,25)) does not show a zero.

Step 3

Exam Tip

वास्तविक शून्यक (x)-अक्ष कटानों से गिने जाते हैं, (y)-अक्ष कटान से नहीं। टिप: ((0,25)) शून्यक नहीं बताता।
