First, gather like terms.
-6 * 9x^3x^2yy^2 - 11xy^3
Then use Product Rule (x^ax^b = x^a+b)
-6 * 9x^(3+2)y^(1+2)-11xy^3
Simplify that.
-6 * 9x^5y^3-11xy^3
Then simplify again.
-54x^5y^3 - 11xy^3
The Greatest Common Factor = xy^3 (if you need my to explain how I got this, just ask).
Then factor the GCF:
xy^3 ( (54x^5y^3)/(xy^3) + (11xy^3)/(xy^3) )
Then simplify
-xy^3(54x^4 + 11)
So unless I am misunderstanding this question, is there a none-of-the-above answer?
