Hello,
Let's get the common denominators 1/a-8 - 2/8-a so it would look like this:
8/8a-(64a/8a) - 2a/8a-(8a^2/8a) This can be combined to get:
(-8a^2-66a+8)/8a Pull out a minus 2 from the numerator to get:
-2(4a^2-33a+4)/8a Reduce 2/8 to:
-(4a^2-33a+4)/4a
It was never stated what was needed with the original so I assumed you wanted it simplified.
