Final answer:
To rewrite the subtraction problem as adding the opposite of the second polynomial, distribute the negative sign to each term within the parentheses and then combine like terms.
Step-by-step explanation:
To rewrite the subtraction problem (x³y² + 2x²y + (-x)) - (x²y + x - 8) as adding the opposite of the second polynomial, you need to distribute the negative sign to each term within the parentheses:
(x³y² + 2x²y + (-x)) - (x²y + x - 8) = x³y² + 2x²y - (-x²y - x + 8)
Now, you can combine like terms and simplify the expression further:
x³y² + 2x²y - (-x²y - x + 8) = x³y² + 2x²y + x²y + x - 8
