To expand the expression (y + 2)( 2y² + 2y + 1), we can use the distributive property and multiply each term of the first expression by each term of the second expression:

(y + 2)( 2y² + 2y + 1) = y * (2y² + 2y + 1) + 2 * (2y² + 2y + 1)

Expanding further:

= 2y³ + 2y² + y + 4y² + 4y + 2

Combining like terms:

= 2y³ + (2<...
