For this case we have the following functions:
[tex]f (x) = 9x ^ 2-2x-9\\g (x) = 11x-9[/tex]
We must find the product of both functions:
[tex]f (x) * g (x) = (9x ^ 2-2x-9) * (11x-9)[/tex]
We apply distributive property term to term:
[tex]f (x) * g (x) = 99x ^ 3-81x ^ 2-22x ^ 2 + 18x-99x + 81[/tex]
We add similar terms:
[tex]f (x) * g (x) = 99x ^ 3-103x ^ 2-81x + 81[/tex]
Answer:
Option B
