Question

I would highly appreciate it if someone could solve these forme.I think I typed them out correctly.
(n-2/n+4)+(8/[n+4])
(5m+8/[m-1]) - (m-3/[m-1])
(x^2/[x-1]) - (1/[x-1])
(4x+y/[2x+3y])-(2x -2y/[2x+3y])
(x^2+3x+2/[x^2-16] + (3x++6/[x^2-16])
7/(x-5) - (2+x/[x-5])

or can someone do a few for me
