Let the 2 consecutive odd integers be represented by:
 “x” and “(x+2)
_________________
The product of these two consecutive odd integers is:
________________
→  x*(x + 2); or, write as: x(x + 2)
__________________
The sum 
of these two consecutive odd integers is:
________________________________
→  x + (x + 2) = (2x + 2)
_______________________________
The product of 2 conductive integers, “
x(x + 2)” , is 1 less than 
   4 times their sum, “(2x + 2)”.
______________________________
→  Write as: 4*(2x + 2) − 1 = x(x + 2)
________________________________
Note the distributive property of multiplication:
_______________________________
→  a*(b + c) = ab + ac ;
________________________________
We have: 
___________
→  4*(2x + 2) − 1 = x(x + 2)
_____________________________
      → 4*(2x + 2) = (4*2x)  + (4*2) = 8x + 8
____________________________________
On the “right side of the equation; we have:
______________________________________
→  x(x + 2) = (x*x) + (x*2) = x² + 2x
_____________________________________
We can rewrite the equation:
__________________________
→  4*(2x + 2) − 1 = x(x + 2) ;
___________________________
by substituting our obtained “expanded values” for:
   “[
4*(2x + 2)]” ; and for: “[x(x + 2)]” ;
______________________________________
→  4*(2x + 2) − 1 = x(x + 2) =
____________________________
         →  8x + 8 − 1 = x² + 2x ;
__________________________________
→ Simplify the “+8 − 1” on the “left-hand side” of the equation to “7”; and subtract “2x” from EACH SIDE of the equation:
____________________________________
→  8x + 7 − 2x = x² + 2x − 2x ; to get:
____________________________
       → 6x + 7 = x² ;
________________________________
→To solve for “x”;  Subtract “6x” and subtract “7”; from EACH SIDE of the equation; to get an equation in “quadratic format” ; that is:
_____________________________________________
ax

let x and x+2 be the consecutive odd integers.
Their product is x(x+2)
Their sum is x + x+2 or 2x+2
x(x+2)=4(2x+2)-1
Domain is odd integers
