Let a be the larger integer and b be the smaller integer. We know that
a = b + 2
since they're consecutive even integers and a is the larger one. Also,

as we are told. Substituting, we get

We use the quadratic formula to get

So b could be 12 or -6, but since the question says the numbers are positive, b must be 12. We conclude that a is 14.
