To simplify the expression (x^5y + x^4y^2 - 3x^5y + 9x^4y^2 - 2x^4y^2), we can combine like terms:

[x^5y - 3x^5y + x^4y^2 + 9x^4y^2 - 2x^4y^2]

Combine the terms with the same variables and exponents:

[x^5y - 3x^5y + x^4y^2 + 9x^4y^2 - 2x^4y^2 = (x^5y - 3x^5y) + (x^4y^2 + 9x^4y^2 - 2x^4y^2)]

[= -2x^5y + 8x^4y^2]

So, the simplified expression is (-2x^5y + 8x^4y^2).
