-Dominant- [34]

Answer:

$(f-g)(x)$

$f(x)-g(x)$

$x^{2} -6x-27-x+9$

$x^{2} -7x-18$

----------------------

$(f*g)(x)$

$=f(x)g(x)$

$(x^{2} -6x-27)(x-9)$

$=x^{3} -15x^{2}+27x+243$

----------------------

$\frac{f}{g} (x)$

$\frac{x^{2} -6x-27}{x-9}$

$\frac{(x-9)(x+3)}{x-9}$

$x+3$

-----------------------

$(f+g)(x)$

$f(x)+g(x)$

$=x^{2} -6x-27+x-9$

$=x^{2} -5x-36$
