Only 3(a−b) and 3a−3b are equivalent
Further explanation:
We have to evaluate each expression to evaluate if the expressions are equivalent or not.
So,
For 3(a−b)
[tex]3(a-b)\\Distributing\ 3\ in\ bracket\\3.a-3.b\\=3a-3b[/tex]
As we can see that 3(a-b) results in 3a-3b so these are equivalent
For 2a(2+b)
[tex]2a(2+b)\\Distributing\ 2a\\2a.2+2a.b\\=4a+2ab[/tex]
As we can see that 2a(2+b) doesn't result in 4ab so these are not equivalent
Hence,
Only 3(a−b) and 3a−3b are equivalent
