Question

if a,b are odd integers thena^2+b^2 =


​

Answer 1

Answer:

will be a positive even number

For example , 3^2 +5^2 = 9 + 25 = 34

Answer 2

Answer:

always even

Step-by-step explanation:

a=(2x+1)

b=(2y+1)

a² + b²

(2x+1)² + (2y+1)²

(4x² + 1 + 4x) + (4y² + 1 + 4y)

4x² + 4y² + 4x + 4y + 2

2 (2x² + 2y² + 2x + 2y + 1)

anything multiplied by 2 is always even.
