Since the denominators are the same you can get right to subtracting.

There is a minus sign splitting the two parts of the equation

Multiply the second half of the equation by -1 because that negative applies to ALL terms

1(a24a+6)2a1

That will then result in

(a2+4a6)

Then combine the equation under one denominator like so

6a27a+8a2+4a62a1

Simplify

5a23a+22a1

Since the numerator cannot be simplified further the final answer is

5a23a+22a1
