Answer:
Vertex (1,-25), Intercepts at (6,0) and (-4,0)
Step-by-step explanation:
Axis of symmetry = -b/2a = -(-2)/2(1) = 2/2 = 1 so x=1 is the equation of line
Plug x=1 into equation y=1-2-24=-25
factor for x-intercepts: (x-6)(x+4)
set them equal to zero: x-6=0 so x=6 x+4=0 so x= - 4
Using the variable x for the unknown number,
20 - (x + 4) = 6
is your answer!
