Answer: 10
Step-by-step explanation:
2x³y³ + 3xy - 3x³y³ +x²y - xy + 2x²y, where x = -1 and y = 2
Now substitute for x and y in the expression above.
2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)
(-2)(8) + (-3)(2) + 3(8) +(1)(2) + (1)(2) + 2(1)(2)
= -16 -6 + 24 + 2 + 2 + 4
= -22 + 32
= 10
