Hello!

You can only add variables with the same base and exponent

8u^3 + 4u^3 = 12u^3
8u^2 + 0 = 8u^2
0 + -6u = -6u
6 + 3 = 9

Put the sums together

12u^3 + 8u^2 - 6u + 9

The answer is [tex]D) 12u^3 + 8u^2 - 6u + 9[/tex]

Hope this helps!

Hello there! Let's calculate this. :)

8u^3+8u^2+6+4u^3−6u+3

=8u^3+8u^2+6+4u^3+−6u+3

Combine Like Terms:

=8u^3+8u^2+6+4u^3+−6u+3

=(8u^3+4u^3)+(8u^2)+(−6u)+(6+3)

=12u^3+8u^2+−6u+9

Answer:

= D. 12u^3+8u^2−6u+9

Cheerio and have a lovely day! ^.^
