Question

Add the following : 1/3a cube—2a square +6;5a cube —a square +6; a cube + 6a square —1


​

Answer 1

Step-by-step explanation:

we are asked to add

a³/3 - 2a² + 6

5a³ - a² + 6

a³ + 6a² - 1

now

a³/3 - 2a²+6+5a³ - a²+ 6+a³ + 6a² - 1

a³/3 +5a³+a³-2a²-a²+6a²+6+6+1

a³/3 +6a³ - 3a²+6a²+13

(18a³+a³)/3 + 3a²+13

19a³/3 + 3a² +13

this is our answer
