Question

The squre of the sum of two odd numbers is?
​

Answer 1

Answer:

Adding two odd integers has a result that ends in “10” and is even. However, an even integer ends in “0”, and its square ends in “00”. Therefore the sum of the squares of two odd integers cannot be the square of an even integer. It cannot be square of an odd integer because that is odd, and the sum is even.

Answer 2

Step-by-step explanation:

Adding two odd integers has a result that ends in “10” and is even. However, an even integer ends in “0”, and its square ends in “00”. Therefore the sum of the squares of two odd integers cannot be the square of an even integer. It cannot be square of an odd integer because that is odd, and the sum is even.
