Step-by-step explanation:

Step 1: Define

2x³y³ + 3xy - 3x³y³ + x²y - xy + 2x²y

x = -1

y = 2

Step 2: Evaluate

Substitute: 2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)Exponents: 2(-1)(8) + 3(-1)(2) - 3(-1)(8) + 1(2) - (-1)(2) + 2(1)(2)Multiply: -16 - 6 + 24 + 2 - (-2) + 4Simplify: -16 - 6 + 24 + 2 + 2 + 4Subtract: -22 + 24 + 2 + 2 + 4Add: 2 + 2 + 2 + 4Add: 4 + 2 + 4Add: 6 + 4Add: 10
