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

यदि (p(x)=(x-c)5(x+d)2), जहाँ \(c\neq -d\), तो अलग शून्यक कौन से हैं?

If (p(x)=(x-c)5(x+d)2), where \(c\neq -d\), what are the distinct zeroes?

Explanation opens after your attempt
Correct Answer

A. (c) और (-d)(c) and (-d)

Step 1

Concept

From (x-c=0) we get (c), and from (x+d=0) we get (-d). Tip: do not count repetition among distinct zeroes.

Step 2

Why this answer is correct

The correct answer is A. (c) और (-d) / (c) and (-d). From (x-c=0) we get (c), and from (x+d=0) we get (-d). Tip: do not count repetition among distinct zeroes.

Step 3

Exam Tip

(x-c=0) से (c) और (x+d=0) से (-d) मिलता है। टिप: अलग शून्यकों में दोहराव न गिनें।
