Answer:
The sum is [tex]6a^2-2ab+2b+9[/tex]
Step-by-step explanation:
Given two expression
[tex](2a^2 + ab + 2b)[/tex] and [tex](4a^2 − 3ab + 9)[/tex]
We have to find the sum of above two expression.
[tex](2a^2 + ab + 2b)+(4a^2 - 3ab + 9)[/tex]
Combining like terms we get
[tex](2a^2+4a^2)+(ab-3ab)+2b+9[/tex]
= [tex]6a^2-2ab+2b+9[/tex]
The sum is [tex]6a^2-2ab+2b+9[/tex]
