You can put this solution on YOUR website! i dont understand how to simplify rational expressions like:
Whatis/are the excluded value(s)
(x^2+3x+1)/(x+5)(x-2)
--------------
The denominator cannot be zero as that would make the fraction "undefined".
---
So, x+5 cannot zero and x-2 cannot be zero
---
So, x cannot be -5 and x cannot be 2.
