Question 238560: Please help solve the following. Please show how you came up with the answer so I can see where I have messed up. Thanks!
Perform the indicated operations and simplify
(these are fractions not dividing)
z-7/z-8-z+1/z+8+z-24/z^2-64
Simplify by removing factors of 1
t^2-1/(t+1)^2

It's not clear what you mean. Add some parentheses.

Simplify by removing factors of 1 (factors of 1?)
t^2-1/(t+1)^2
This could be t^2 - (1/(t+1)^2, but I think it's
(t^2-1)/(t+1)^2
= (t+1)*(t-1)/(t+1)^2
= (t-1)/(t+1)
