Answer: 2d³+11d²+19d+10
Step-by-step explanation:
Use the FOIl method to simplify this
-------------------------------------------------------------------
(5+2d)(2+3d+d²)
=10+15d+5d²+4d+6d²+2d³ ⇔ Expand using FOIL
=2d³+(5d²+6d²)+(4d+15d)+10 ⇔ Put like terms together
=2d³+11d²+19d+10 ⇔ Combine like terms
Hope this helps!! :)
