Simplify the following:
(2y + 1)(4y^10 + 2y^9 + 4y^8 + 2y^7 + 2y^6 + 4y^5)
Express your answer as a polynomial with the degrees of the terms in decreasing order.
(2y + 1)(4y10 + 2y9 + 4y8 + 2y7 + 2y6 + 4y5)
= 8y11 + 4y10 + 4y10 + 8y9 + 2y9 + 4y8 + 4y8 + 4y7 + 2y7 + 8y6 + 2y6 + 4y5
= 8y11 + 8y10 + 10y9 + 8y8 + 6y7 + 10y6 + 4y5
