Sorry that came out a bit messier than I had intended. It should read 2x squared minus 8x over x squared minus 16, divided by 8x squared over (x+4)squared.
Spaces can't be handled on the board. The best way to write a problem is to use parentheses. For example,
x-2 divided by 3 + 4 divided by x and the 4 divided by x is squared.
[(x-2)/3] + (4/x)^2 = etc.
x-2 divided by 3 + 4 divided by x and the 4 divided by x is squared.
[(x-2)/3] + (4/x)^2 = etc.
Haha thanks, I learned the hard way but now I know.
