Answer:

-17a⁴

Step-by-step explanation:

12a⁴ + (-29a⁴) = 12a⁴ -29a⁴ = -17a

Answer:

= [tex]-17a^{4}[/tex]

Step by Step Explanation:

For this question, we must combine like terms.

[tex]= 12a^{4} + -29a^{4}[/tex]

[tex]= (12a^{4} + -29a^{4})[/tex]

Now, we must flip the equation around and subtract.

Keep the variables and exponents where they are.

[tex]= -29a^{4} - 12a^{4} = 7a^{4}[/tex]

We now have our answer.
