x = first odd integer
x + 2 = second odd integer {consecutive odd integers increase by two}
x(x + 2) = (x + 2)² - 22 {product of two consecutive odd integers is 22 less than square of greater}
x² + 2x = (x + 2)(x + 2) - 22 {used distributive property on left, when you square a binomial, multiply it by itself}
x² + 2x = x² + 4x + 4 - 22 {used foil method on right}
x² + 2x = x² + 4x - 18 {combined like terms}
2x = 4x - 18 {subtracted x² from each side}
-2x = -18 {subtracted 4x from each side}
x = 9 {divided each side by -2}
x + 2 = 11 {substituted 9, in for x, into x + 2}
9 and 11 are the two consecutive odd integers
