Correct Answer

A. (x=6) पर स्पर्श करेगाIt will touch at (x=6)

Step 1

Concept

(6x-2-72x+216=6(x-6)2), so it touches at (x=6). Tip: the outside (6) does not change the zero.

Step 2

Why this answer is correct

The correct answer is A. (x=6) पर स्पर्श करेगा / It will touch at (x=6). (6x-2-72x+216=6(x-6)2), so it touches at (x=6). Tip: the outside (6) does not change the zero.

Step 3

Exam Tip

(6x-2-72x+216=6(x-6)2) है, इसलिए (x=6) पर स्पर्श होगा। टिप: बाहरी (6) शून्यक नहीं बदलता।
