I assume this problem is a factoring problem

Step 1. Need to find two integers m and n such that their sum m+n=-29 and their product is m*n=3*18=54.

Step 2. After a couple tries, the integers are -2 and -27.

Step 3. We can now factor the equation using grouping and noting that .

Factor x in the first group and -9y in the second group

Now factor 3x-2y since it is common to both groups

Step 4. ANSWER:

I hope the above steps and explanation were helpful.
