Answer:  
Step-by-step explanation:
 Given the following expression shown in the picture:
 
You need to use a process called "Ratinalization".
 By definition, using Rationalization you can rewrite the expression in its simplest form so there is not Radicals in its denominator.
 Then, in order to simplify the expression, you can follow the following steps:
 <em>Step 1</em>. You need to multiply the numerator and the denominator of the fraction by  
, which is the conjugate of the denominator  
.
<em>Step 2</em>. Then you must apply the Distributive property in the numerator.
 <em>Step 3</em>. You must apply the following property in the denominator:  
 
 Therefore, applying the procedure shown above, you get:
 
 <em>Step 4</em>.  You can observe that the expression can be simplified even more. Since:
  
 You get:
 
 
        
             
        
        
        
Answer: 
 y=mx+b is the formula starting with b say it is 4 you put a dot on 4  on the y axis m is 1/2 you go up 1 right 2 on the 4 points then do the same on the next point you get then you get your line. hope this helps  
 
        
             
        
        
        
Answer:
1. 

2. 

3. 

Step-by-step explanation:
1. The given polynomial is

We need to factor the second part to get:

We factor y-5 to obtain:

2. We have 

We again factor -1 from the second part to get:

We now factor x-y to get:


3. We have 

We factor negative 1 from the first part to get

We now factor b-3 to get:

We now simplify to get:
