Answer:
x = - 4 ± 2
Step-by-step explanation:
Given
f(x) = x² + 8x + 4
To find the zeros let f(x) = 0, that is
x² + 8x + 4 = 0 ( subtract 4 from both sides )
x² + 8x = - 4
To solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = - 4 + 16
(x + 4)² = 12 ( take the square root of both sides )
x + 4 = ±  = ± 2
 = ± 2 ( subtract 4 from both sides )
 ( subtract 4 from both sides )
x = - 4 ± 2
Thus the zeros are
x = - 4 - 2 and x = - 4 + 2
 and x = - 4 + 2
 
        
             
        
        
        
1) (-4,0)lowest and highest x values 
2) (2,3)lowest and highest y values 
3) (-2,0] point where the graph is going down 
5) x-intercept is (-3,-1)
