Question 238247: find domain for function h
h(x) =15/x^2+6x+5

It depends.
Do you mean:
\ =\ \frac{15}{x^2}\ +\ 6x\ +\ 5)
or
\ =\ \frac{15}{x^2\ +\ 6x\ +\ 5})
Either way, set the denominator equal to zero and solve. The roots of this equation will be the values excluded from the rational function. The domain is all other real numbers.
