Question
Add, subtract, or multiply, as indicated. Express your answer as a single polynomial in standard form.$$8\left(1-y^{3}\right)+4\left(1+y+y^{2}+y^{3}\right)$$
Step 1
This gives us: \[8(1) - 8(y^{3}) + 4(1) + 4(y) + 4(y^{2}) + 4(y^{3})\] which simplifies to: \[8 - 8y^{3} + 4 + 4y + 4y^{2} + 4y^{3}\] Show more…
