For this case we have the following functions:

[tex]f (x) = 3x ^ 3-7x ^ 2-9x + 21\\g (x) = 3x-7[/tex]

We must find the value of the following expression:

[tex]\frac {f (x)} {g (x)}[/tex]

So:

[tex]\frac {f (x)} {g (x)} = \frac {3x ^ 3-7x ^ 2-9x + 21} {3x-7}[/tex]

Looking at the attached image we have to:

[tex]\frac {f (x)} {g (x)} = x ^ 2-3[/tex]
