Answer:
-q^2-q+72
Step-by-step explanation:
We can use the FOIL (First Outer Inner Last) method for this. First, multiply 9*8 (72). Then, multiply 9*-q(-9q). After that, multiply q*8 (8q). Finally, multiply q*-q(-q^2). Arrange the different terms:
-q^2-9q+8q+72
Finally, combine like terms:
-q^2-q+72
Hope this helps!
