You must add together terms that have the same kind of variables (such as

a^{3}

)
according to their numerical values (with sign):
for example:
You can add:

5 a^{3} + 2 a^{3} = 7 a^{3}

the variables are of the same kind

a^{3}

so you simply add the mumerical values;
You cannot add:

5 a^{3} + 3 a^{2}

the variables are different!!!!
You add together, according to their sign, single numbers (without variables).
If you add correctly, you should get

3 a^{3} + 4 a^{2} - a + 5

Do you have a similar question?

Recalculate according to your conditions!
