just multiply
remember the distributive proeprty a(b+c)=ab+ac
(f *g)(x)=f(x)g(x)=(1/x)(x^2+5x)=(x^2/x)+(5x/x)=x+5

(f*g)(x)=x+5

Answer:

(f×g)(x) = x +5.

Explanation:

Given : f(x)=
(1)/(x) and g(x) = x²+5x.

To find : find (f×g)(x).

Solution: We have given f(x)=
(1)/(x) and g(x) = x²+5x.

For (f×g)(x) = f(x) * g(x) .

Plug the values

(f×g)(x) =
(1)/(x) * x²+5x.

(f×g)(x) =
(x^(2)+5x )/(x)

On taking x common from the numerator

(f×g)(x) =
(x(x+5))/(x).

(f×g)(x) = x +5.

Therefore, (f×g)(x) = x +5.
