An expansion means the image gets larger, so the scale factor has to be larger than 1.

The sign of the number ( either positive or negative) doesn't affect the scale, so to find the scale for an enlargement you can ignore the negative sign.

This would give you two numbers larger than 1, both -8 and 7 would be the correct scale factors.
