First, find the sum of 8n^2-9n-2 and -3n^2+n+4. To do this, combine "like" terms. Like terms are those which have the same exponent of n.

Next, subtract this from -13n^2-n+9. This is written as follows:

change - to a + and invert sign of all terms to right of minus:

Next, combine like terms again:
