Simplify. Assume no denominators are 0. Show cancelling and factoring.
(y^2-49/z^2+z) divided by (y+7/z)

Flip and multiply.

Factor where possible.
Side work:
y^2-49 = y^2 - 7^2, which is the difference of two squares which can easily be factored as (y+7)(y-7)
z^2+z can factor out a z to get z(z+1).
With that in mind:
