Answer:

4u^3 + 6u^2 - 7u + 9

Step-by-step explanation:

(2u3 + 6u2 + 3) + (2u3 – 7u + 6)

Remove the brackets.

2u^3 + 6u^2 + 3 + 2u^3 - 7u + 6

2u^3 + 2u^3 = 4u^3

6u^2

- 7u

3 + 6 = 9

Now just read down

4u^3 + 6u^2 - 7u + 9

The answers don't seem to connect with the question. Is U equal to something?
