In my physics books it gives an equation of frequency for a moving observer as f'= v'/λ =v+u/λ. Since λ=v/f it was converted to f'=v+u/(v/f) = (v+u/v)f I understand this much of the equation, but the final Algebraic factoring that I don't get is they said this equation is f'=...

Yes but I figured out the answer with that specific equation. I guess I just didn't think of dividing it out. Error on basic Algebra.

Thank you so much. I don't know where I went wrong with that one.
