Answer:
[tex]3a^3+4a^2-1a+5[/tex]
Step-by-step explanation:
Add the following polynomials:
[tex]3a^3 + 8a - 6 \ and\ 4a^2 - 9a + 11[/tex]
To add the polynomials we combine like terms
[tex]3a^3 + 8a - 6 + 4a^2 - 9a + 11[/tex]
The terms with same variables are like terms
8a and -9a are like terms
8a - 9a = -1a
-6 +11= 5
[tex]3a^3 + 8a - 6 + 4a^2 - 9a + 11=3a^3+4a^2-1a+5[/tex]
