Given:
Two roots of a function are 10 and 
.
To find:
The additional roots.
Solution:
According to irrational root theorem, if 
 is a root of a function, then 
 is also a root of than function.
Two roots of a function are 10 and 
.
Using irrational root theorem, we can say that 
 is also a root of that function.
Therefore, the additional root is 
.
