-------------------------------------
Determine the value(s) of the variable for which a) the expression equals zero b) the expression is undefined.
15 -5d / d^2 + 25
---------------------------------------
Assuming your expression is (15-5d)/(d^2-25),
It is defined for all real numbers d, and the only value making the expression 0 is for d=3. Denominator will never be 0 here.
