Question 844154
{{{f(x)=6/x}}}
{{{g(x)=x/(x-8)}}}
.
.
{{{f+g=6/x+x/(x-8)}}}
{{{f+g=(6(x-8))/(x(x-8))+x^2/(x(x-8))}}}
{{{f+g=(6x-48+x^2)/(x(x-8))}}}
{{{f+g=(x^2+6x-48)/(x(x-8))}}}
Similarly,
{{{f-g=(6x-48-x^2)/(x(x-8))}}}
{{{f-g=(-x^2+6x-48)/(x(x-8))}}}
.
.
{{{f*g=(6/x)(x/(x-8))=6/(x-8)}}}
.
.
{{{f/g=(6/x)*((x-8)/x)=(6(x-8))/x^2}}}
