prove that if x and y are odd positive integers, then x square +y square is even but not divisible by 4 |
Answer» Answer:-Thinking Process:- Here, we have to take any two consicutive or positive integer. After that squaring and adding both the number and CHECK it is a even but not divisible by 4. Solution:- Let x = 2m + 1 Let y = 2m + 3 Here, both are positive integer, for every positive integer m. ⇒ x² + y² = (2m +1)² + (2m + 3)² ⇒ x² + y² = 4m² + 1 + 4m + 4m² + 9 + 12m [∵ (a + B)² = a² + 2AB + b²]
⇒ x² + y² = 8m² + 16m² + 10 = even ⇒ x² + y² = 2(4m² + 8m + 5) or (2m² + 4m + 2) Hence, x² + y² is even for every positive integer m but not divisible by 4. |
