Final answer:
To find the product of -y(2y 3 - 8), distribute -y to each term inside the parentheses and combine like terms.
Step-by-step explanation:
The product of -y(2y 3-8) can be found by distributing the -y to each term inside the parentheses.
Step 1: Multiply -y by 2y: -y(2y) = -2y^2
Step 2: Multiply -y by 3: -y(3) = -3y
Step 3: Multiply -y by -8: -y(-8) = 8y
Combining the terms, the product is -2y^2 - 3y + 8y.
