$$2x^2y^3 + 3xy + 12y^2$$
When you subtract a polynomial, you add the opposite of that polynomial. We can now rewrite the problem without parentheses: $$8x^2y^3 - xy + 2y^2 - 6x^2y^3 + 4xy + 10y^2$$ Group like terms: $$(8x^2y^3 - 6x^2y^3) + (-xy + 4xy) + (2y^2 + 10y^2)$$ Combine like terms: $$2x^2y^3 + 3xy + 12y^2$$
