Answer:
x=0
Step-by-step explanation:
(x – 3)(x + 9) = –27
To get the solution we solve for x
(x – 3)(x + 9) = –27
USe FOIL method to multiply (x – 3)(x + 9)
x^2 +9x-3x-27
x^2 + 6x - 27
(x – 3)(x + 9) = –27
x^2 + 6x - 27=-27
Add 27 on both sides
x^2 + 6x=0
x(x+6)=0
x=0 and x+6 =0
x=0 , x=-6
So x=0 is one of the solution
Your answer would be x = 0

you should make the picture more clear, i cant see the answer choices
The x-intercepts are readily identified on the graph: (2,0) and (4,0). The midpoint of a line connecting those 2 points would be (3,0).
-2*4=-8
-8 is the correct answer
