A= 320 cm2 and that is the answer
(x+6)×(x+2) use photomath if you have a smart phone it helps a lot
Convert the equation into a standard form
y=x2+4x+4
y= (x+2)^2
From the equation
vertex is located at (-2,0)
Solve for a to get the coordinates of the focus, from the equation
4a=1
a=1/4
Focus is located at (-2, 1/4)
The equation of the directrix
y=-1/4
