The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.
The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).
Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).

Answer:
Mean= 10.83
Median= 9.5
Step-by-step explanation:
Given number,
10, 15, 8, 11, 9, 12
N= 6
As we know,
Mean= Ex/N
=10+15+8+11+9+12/6
=65/6
=10.83
Therefore, Mean= 10.83
Now,
Median(MD)= (N+1/2)th item
= 6+1/2
=7/2
=3.5th item
So, Median(MD)= 3th+4th/2 item
= 8+11/2
= 19/2
= 9.5
Therefore, Median= 9.5
Answer:
Step-by-step explanation:
has the form 
known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.
The factored for is (a+b)(a-b).
In this case, it is
