Answer:

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

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

Step-by-step 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
