According to the given question the result of f(x)*g(x) is obtained by finding the product of the expressions for f and g respectively, this way:
[tex]\begin{gathered} f(x)\cdot g(x) \\ (11x^3-3x^2)\cdot(7x^4+9x^3) \\ 77x^7+99x^6-21x^6-27x^5 \\ 77x^7+78x^6-27x^5 \end{gathered}[/tex]
The answer is A.
