Answer:

$\huge {\mathbb{\blue{HELLO!!}}}$

The image distance (u) is always negative as it is placed to the left side of the mirror. If an image is formed behind a concave mirror (to the right side), the image distance (v) is positive but if the image is formed in front of the mirror (on the left side), then the image distance will be negative.
