Question Easy Mathematics Quadratic Equations Nature of Roots Class 10 Level 37

यदि (D=0) और \(a\neq0\) हो तो द्विघात समीकरण में कितने अलग-अलग वास्तविक मूल होंगे?

If (D=0) and \(a\neq0\), how many distinct real roots will the quadratic equation have?

Explanation opens after your attempt
Correct Answer

A. (1)

Step 1

Concept

At (D=0), both roots are equal, so the number of distinct real roots is (1). Remember the root is repeated.

Step 2

Why this answer is correct

The correct answer is A. (1). At (D=0), both roots are equal, so the number of distinct real roots is (1). Remember the root is repeated.

Step 3

Exam Tip

(D=0) पर दोनों मूल समान होते हैं, इसलिए अलग-अलग वास्तविक मूलों की संख्या (1) है। ध्यान रखें मूल दो बार दोहरता है।

Question Medium Mathematics Polynomials Geometrical meaning of the zeroes of a polynomial. Class 10 Level 24

यदि किसी ग्राफ के बिंदु ((3,0)) और ((3,0)) एक ही स्पर्श को दो बार दिखा रहे हैं तो अलग शून्यक कितने हैं?

If the points ((3,0)) and ((3,0)) show the same touch twice on a graph, how many distinct zeroes are there?

Explanation opens after your attempt
Correct Answer

A. एकOne

Step 1

Concept

Both have the same (x)-value (3), so there is one distinct zero. Tip: count a repeated value once for distinct count.

Step 2

Why this answer is correct

The correct answer is A. एक / One. Both have the same (x)-value (3), so there is one distinct zero. Tip: count a repeated value once for distinct count.

Step 3

Exam Tip

दोनों में (x)-मान समान (3) है इसलिए अलग शून्यक एक है। टिप: दोहराए मान को अलग गिनती में एक बार लें।
