The diagram shows the terms x^2 and 18 as result of x*x and (-3) * (-6).

The two terms that are missing come from x * (-3) and (-6) * x.

That is: x * (-3) = - 3x and (-6) * x = - 6x.

So the two terms missing are - 3x and - 6x.

As you can see x^2 - 3x - 6x + 18 = x^2 - 9x + 18, that is the original polynomial.

Answer: - 3x and - 6x.
