Answer:

15u^3+8u^2 -3u+14

Step-by-step explanation:

Like terms are those terms which have same variable  to the same power.

Simplify:

(7u^3+8u^2+7)+(8u^3 -3u+7)

Remove the bracket:

7u^3+8u^2+7+8u^3 -3u+7

Combine like terms;

15u^3+8u^2 -3u+14

Therefore, the sum of (7u^3+8u^2+7)+(8u^3 -3u+7) is, 15u^3+8u^2 -3u+14
