Correct Answer

A. (x=-3) पर स्पर्श करेगाIt will touch at (x=-3)

Step 1

Concept

(2x-2+12x+18=2(x+3)2), so it touches at (x=-3). Tip: the outside (2) does not change the zero.

Step 2

Why this answer is correct

The correct answer is A. (x=-3) पर स्पर्श करेगा / It will touch at (x=-3). (2x-2+12x+18=2(x+3)2), so it touches at (x=-3). Tip: the outside (2) does not change the zero.

Step 3

Exam Tip

(2x-2+12x+18=2(x+3)2), इसलिए (x=-3) पर स्पर्श होगा। टिप: बाहरी (2) शून्यक नहीं बदलता।
