it said i was correct :P
 
        
                    
             
        
        
        
Answer:
(x + 3) ( x - 6)
Step-by-step explanation:
x² - 3x - 18
x² - 6x + 3x - 18
x(x - 6) + 3(x - 6)
(x + 3) ( x - 6)
 
        
                    
             
        
        
        
Answer:
87/3
Step-by-step explanation:
Here we are given the expression:

Now we have to find the value of this expression when x equals 9.
So plugging the value of x as -9 in the given expression:


=87/3
So on evaluating we get the value of expression as 87/3.
 
        
                    
             
        
        
        
Okay so basically the answer would be 4/15
        
             
        
        
        
First find the critical points of <em>f</em> :



so the point (1, 0) is the only critical point, at which we have

Next check for critical points along the boundary, which can be found by converting to polar coordinates:

Find the critical points of <em>g</em> :



where <em>n</em> is any integer. We get 4 critical points in the interval [0, 2π) at




So <em>f</em> has a minimum of -7 and a maximum of 299.
