Correct answer only ! factor the expression completely over the complex numbers. y3 + 2y2 + 16y + 32

     y³ + 2y²      +       16y + 32

= y²(y + 2)        +     16(y + 2)

= (y² + 16) (y + 2)

Note: y² + 16  = y² - (-16)   is the difference formula: √(y²)  - √(-16)²  = (y + 4i)(y - 4i)

(y - 4i)(y + 4i)(y + 2)
