%28-12x%5E2y+-+9x%5E5y%5E2-+15+xy%5E4%29%2F%28-3xy%29 Start with the given expression


%28-12x%5E2y%29%2F%28-3xy%29+-+%289x%5E5y%5E2%29%2F%28-3xy%29-+%2815+xy%5E4%29%2F%28-3xy%29 Break up the fraction


Divide the variables. Remember when you divide monomials, you subtract their corresponding exponents.


4x%5E1y%5E0+%2B3x%5E4y%5E1%2B5x%5E0y%5E3 Simplify. Remember to reduce the coefficients.


4xy%5E0+%2B3x%5E4y%2B5x%5E0y%5E3 Remove the exponents of 1 since x%5E1=x.


4x+%2B3x%5E4y%2B5y%5E3 Remove the terms with the exponents of 0 since x%5E0=1.

Answer:
So %28-12x%5E2y+-+9x%5E5y%5E2-+15+xy%5E4%29%2F%28-3xy%29 simplifies to 4x+%2B3x%5E4y%2B5y%5E3
