Answer 2

Sum of
`7a^3+14a+12\ and\ -6a^3+12a^2-7` is:

`a^3+12a^2+14a+5`

Explanation:

We have to find the sum of
`7a^3+14a+12\ and\ -6a^3+12a^2-7`

`7a^3+14a+12+(-6a^3+12a^2-7)`

`=7a^3+14a+12-6a^3+12a^2-7`

`=a^3+12a^2+14a+5`

Hence, sum of
`7a^3+14a+12\ and\ -6a^3+12a^2-7` is:

`a^3+12a^2+14a+5`
