Hard Mathematics Polynomials Class 10 Level 24

यदि (p(x)=x-2-6kx+9k-2) है तो ग्राफ (x)-अक्ष को किस (x)-मान पर स्पर्श करेगा?

If (p(x)=x-2-6kx+9k-2), at which (x)-value will the graph touch the (x)-axis?

Explanation opens after your attempt
Correct Answer

B. (x=3k)

Step 1

Concept

It is ((x-3k)2), so the repeated zero is (3k). Tip: identify the perfect square form quickly.

Step 2

Why this answer is correct

The correct answer is B. (x=3k). It is ((x-3k)2), so the repeated zero is (3k). Tip: identify the perfect square form quickly.

Step 3

Exam Tip

यह ((x-3k)2) है इसलिए दोहराया शून्यक (3k) है। टिप: पूर्ण वर्ग रूप को तुरंत पहचानें।
