Domain:All x values except those that make the denominators equal to zero.
{{{x=0}}}
{{{x=4}}}
or in interval notation, ({{{-infinity}}},{{{0}}})U({{{0}}},{{{4}}})U({{{4}}},{{{infinity}}})
.

.

{{{(x-2)/(x-4) = 8/(x^2-4x)}}}
{{{(x(x-2))/(x(x-4)) = 8/(x(x-4))}}}
{{{(x(x-2)- 8)/(x(x-4))=0}}}
{{{(x^2-2x-8)/(x(x-4))=0}}}
{{{((x-4)(x+2))/(x(x-4))=0}}}
{{{(x+2)/x=0}}}
{{{highlight(x=-2)}}}
