Let the first odd integer = 2n - 1   and let the second = 2n + 1    so we have

 

(2n - 1)^2  +  (2n + 1)^2   = 74

 

4n^2  - 4n + 1  + 4n^2 + 4n + 1   =  74

 

8n^2 + 2  =74

 

8n^2  = 72     

 

n^2  = 9

 

n = 3

 

So....the two integers are  2(3) - 1   = 5   and  2(3) + 1  = 7

 

 

cool cool cool
