Let E1 and E2 be two even numbers. Then (E1+1)(E2+1) will be the product of two odd numbers. We have E1*E2 +E2+E1+1. Now when we add or multiply even numbers, we get even numbers and we add 1, it's odd.
The two numbers that add to give you 25 and multiply to give you 26 are 24 and 1. When you add 24 and 1, you get 25, and when you multiply them, you get 26.
The two numbers that add to give 1 and multiply to give -4 are 4 and -3. When you add them, 4 + (-3) = 1, and when you multiply them, 4 × (-3) = -12. So, the correct answer is 4 and -3.
