Answer:
Sum of [tex]7a^3+14a+12\ and\ -6a^3+12a^2-7[/tex] is:
[tex]a^3+12a^2+14a+5[/tex]
Step-by-step explanation:
We have to find the sum of [tex]7a^3+14a+12\ and\ -6a^3+12a^2-7[/tex]
[tex]7a^3+14a+12+(-6a^3+12a^2-7)[/tex]
[tex]=7a^3+14a+12-6a^3+12a^2-7[/tex]
[tex]=a^3+12a^2+14a+5[/tex]
Hence, sum of [tex]7a^3+14a+12\ and\ -6a^3+12a^2-7[/tex] is:
[tex]a^3+12a^2+14a+5[/tex]
