# Extract the factor Watch

1. I'm not sure what the attached question means. Is it that I take the factor out as I would a common factor? But then, since the factor isn't common, within the brackets the same factor would be generated again e.g. the answer for a) would be: σλ(1-(4/σλ)). I don't think that's right though.

Aside from the fact that you've changed a plus sign to a minus, I agree with that answer.
