Undetermined Coefficients. 163 



16. If we wish to develope the algebraic sum of two or more 

 radicals it is best to develope each one by itself and then find the 

 algebraic sum of the results. 



17. Examples. 



/ . Develope 1 1 — ' , . 



2. Develope ^|-^+ 7^+ V i H--^'. 



Develope V i -h \x -\- (yx"" -f bx ^ + 5 jf •* -}- 2 jr ^ -f x^\ 



J" 



2 I 

 4. Develope J^x^ -^ 2 x -\- ^-\ f--^.
