To simplify the expression (2a^2+10a)/(3a^2+15a), we can factor out a common factor of 2a from both the numerator and denominator. This gives us (2a(a+5))/(3a(a+5)).

Next, we can cancel out the common factor of (a+5) from both the numerator and denominator. This leaves us with 2a/3a, which simplifies to 2/3.

To find the excluded values, we need to identify the values of 'a' that would make the denominator equal to zero. In this case, if we set 3a^2+15a equal to zero and solve for 'a', we get a = 0 and a = -5. Therefore, the excluded values are a = 0 and a = -5.
