find three consecutive positive odd integers such that the sum of the squares of the first and second integers is equal to the square of the third integer minus 7
***
let x=1st consecutive odd integer
let x+2=2nd consecutive odd integer
let x+4=3rd consecutive odd integer
..
x^2+(x+2)^2=(x+4)^2-7
x^2+x^2+4x+4=x^2+8x+16-7
x^2-4x-5=0
(x-5)(x+1)=0
x=5
x+2=7
x+4=9
three consecutive positive odd integers are: 5, 7, 9
