Bear in mind that, if you multiply any integer, by 2, you always get an EVEN number, no matter whatsoever what that integer is. Say 2*2 = even, 17*2= even, 37*2 = even and so on.
So, let's pick a reference integer, say "a", so, 2 * a, we know is an EVEN integer, so our first integer is 2a then.
Now, to get a consecutive integer from any even integer, all you do is, hop backwards one spot, or forwards one spot, like say, 2 + 2, or 2-2, or 6 + 2, or 6 -2 and so on.
Therefore, since our first even integer is 2a, then the next one can just be say, 2a + 2.
Now, we know their product is 440, thus
so.. recall that "a" was only our reference integer, so the even number integers are then 2a and 2a + 2, or 2(10) and 2(10) + 2.
