Answer:
Pretty sure it's ab + ab
Step-by-step explanation:
Taking the test myself.. if it needs to be even for all integers and it doesn't give us numbers for a or b then ab + ab is the only "even for all integers"
Considering that the multiplication of a number by 2 always results in an even number, the correct option is:
E) ab + ab
In option E, the equivalent expression is:
[tex]ab + ab = 2ab[/tex]
A number multiplied by 2 is always even, thus, the expression is even for all integers.
