HELP I don’t know how to multiply when the f(x) is separated

Look at the expl. first-

a x^2 -13x + 22

b x^2 -9x -2

c x^{4\ }-\ 18x^{3}\ +72x^{2}\ +\ 81x

d x-4

Step-by-step explanation:

Basically, the circle in the middle means "of", so i need to give u an example. f circle g or "f of g" as it is more commonly used means that you put the expression after "of" into the equation before "of" as x. In f of g, you put x-2 in the f(x) equation, which results to x^2 -13x + 22.
