Question 647239

this problem like this x-3/x+2 {x|x=-2|

{{{ (x^2-1)/(x-5)}}}..........since you have rational expression, the denominator cannot be equal to zero because to divide by zero doesn't make sense

so, the domain is all real numbers except one that makes denominator equal to zero and it is {{{x-5=0}}}...->...{{{x=5}}}

your answer is: {x|x=5|
