Find the sum of these two trinomials.
(4a^3 – 5a^2 + 6a) + (a^3 + 2a - 3)

(4a^3 – 5a^2 + 6a) + (a^3 + 2a - 3)

Remove parentheses:

4a^3 – 5a^2 + 6a + a^3 + 2a - 3

Group like terms:

4a^3+a^3-5a^2+6a+2a-3

Add similar elements 4a^3+a^3:

4a^3+a^3= 5a^3

5a^3 -5a^2+6a+2a-3

Add similar elements 6a+2a:

6a+2a= 8a

5a^3-5a^2+8a-3

Your Answer Is 5a^3-5a^2+8a-3
