यदि (p(x)=x-2-9), तो (p(x)) के शून्यक कौन-से हैं?

If (p(x)=x-2-9), what are the zeroes of (p(x))?

Explanation opens after your attempt
Correct Answer

A. (3,-3)

Step 1

Concept

(x-2-9=(x-3)(x+3)), so the zeroes are (3) and (-3). Identify difference of squares quickly.

Step 2

Why this answer is correct

The correct answer is A. (3,-3). (x-2-9=(x-3)(x+3)), so the zeroes are (3) and (-3). Identify difference of squares quickly.

Step 3

Exam Tip

(x-2-9=(x-3)(x+3)), इसलिए शून्यक (3) और (-3) हैं। वर्गों के अंतर को तुरंत पहचानें।
