Question 92652
If x and y are positive consecutive odd integers, where y > x, which of the following is equal to If x and y are positive consecutive odd integers, where y > x, which of the following is equal to y^2-x^2? 
:
Let y = (x+2)
:
Substitute (x+2) for y and you have: 
(x+2)^2 - x^2
:
x^2 + 4x + 4 - x^2; FOILed (x+2)(x+2)
:
4x + 4
