Answer:
The additive inverse is equal to [tex]-2a-b[/tex]
Step-by-step explanation:
we know that
The additive inverse of a number is equal to its opposite ( the sum of a number and its additive inverse is equal to zero)
so
we have
[tex]2a+b[/tex]
Multiply by -1
[tex]-1(2a+b)=-2a-b[/tex]
therefore
The additive inverse is equal to [tex]-2a-b[/tex]
