Math help? Please??? The function h is defined below. h(x)=x+3/x^2-4x-5 Find all values of x that are NOT in the domain of h. If there is more than one value, separate them with commas.

hartnn (hartnn):

the values of 'x' for which denominator of h(x) =0 are those NOT in the domain of h so, solve, x^2-4x-5 =0 and 2 roots of 'x' will not be in the domain, can you solve that ?

-1,5

hartnn (hartnn):
