Answer:
The rational zero of the polynomial are  .
  .  
Step-by-step explanation:
Given polynomial as :
f(x) = 4 x³ - 8 x² - 19 x - 7
Now the ration zero can be find as 
 ,
 , 
where P is the constant term
And Q is the coefficient of the highest polynomial 
So, From given polynomial ,  P = -7 , Q = 4
Now , 
I.e   =
 =  
 
Or, The rational zero are 
Hence The rational zero of the polynomial are  .  Answer

Answer:
Step-by-step explanation:
See the attached image
 
        
             
        
        
        
5x - y = 1/4; this equation is written in slope - intercept form
Slope - Intercept form formula: y = mx + b
-Move '5x' to the left side of the equation
-Move 'y' to the right side of the equation
y = 5x - 1/4
        
             
        
        
        
Step-by-step explanation:
first collect terms, while the < remains unchange
<u>P</u><u> </u><u> </u>< 1-2
9
cross examine and get the answer
<u>P</u><u> </u>< <u>-</u><u>1</u>
9 1
<em>P</em><em> </em><em>=</em><em> </em><em>-</em><em>9</em>
 
        
             
        
        
        
The other factor is (y - 3).  If you multiply the two terms together, you will end up with
