Question

write rationalizing factor of x+√x when x=3​

Answer 1

Answer:

We know that If the product of two surds is a rational number, then each factor is a rationalising factor of the other.

Now multiply  

xy

​

 to itself to make  

xy

​

 a rational number as shown below:

⇒(  

xy

​

)×(  

xy

​

)=xy  

Hence,  

xy

​

 is the rationalising factor of  

xy
