Step-by-step explanation:

The given expression is

To solve this division, we could find the solution factors of each expression.

So, let's work on the numerator first

First, we need to express this in two factors, where the sign of the first factor would be the same as the second term of the given expression (negative). And the sign of the second factor would be the product of the sign of the second factor term and the third term. As follows

So, and would be two number which product is 54 and its subtraction is 3. You would find that 9 and 6 are those number because

Therefore, the solution factors are

Then, we do the same process with the denominator

In this case, we needed to find to number which product is 81 and which sum is 18.

Now, we replace all these factor into the given fraction.

Therefore, most simple form of the given expression is
