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