Answer:

Explanation:
The arithmetic operation of the two equations presented in this case can be solved as a division of polynomials.
We can write the problem as:

We need not to forget the negative in the denominator. Then we can factor the numerator as follows:

Now we can easily spot the solution, and get there with the following steps:

As I said earlier we need to remember that the negative will change the symbols in the equation once we factor the polynomial.
And like that we get to the answer:
