Expand and simplify the following: (5+2d)(2+3d+d²)

Must show working !! Will give brainliest :)

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!! :)

Please let me know if you have any questions

2d³+11d²+19d+10

Step-by-step explanation: first we rearrange terms (5+2d)(2+3d+d²) into (2d + 5)(2 + 3d + d^2) then we do Rearrange terms again and then we Distribute and combine like terms and get our answer.

to rewrite a literal equation you may need to divide by a number, or by a variable.
