Simplify the sum. (2u3 + 6u2 + 2) + (7u3 – 7u + 4)

Sum is 9u³ + 6u²  - 7u + 6 .

Step-by-step explanation:

Given : (2u³+ 6u² + 2) + (7u³ – 7u + 4)

To find: Simplify the sum.

Solution : We have given (2u³+ 6u² + 2) + (7u³ – 7u + 4).

On removing the parenthesis

2u³+ 6u² + 2 + 7u³ – 7u + 4.

Combining like terms

2u³ + 7u³ +  6u²  -7u +2 + 4.

9u³ + 6u²  - 7u + 6 .

Therefore, Sum is 9u³ + 6u²  - 7u + 6 .
