Let the integers be n, n+1, and n+2.
The product of the first two is
That plus the third integer is
If --> (subtracting 2 from both sides).
Now we can complete the square to solve the quadratic equation:
--> --> -->
The integers are 9, 10, and 11.
NOTE: There are other ways to solve that quadratic equation (factoring, the quadratic formula), but completing the square looked easier.
