Answer:
Step-by-step explanation:
The not simplified form is
you know that is true a and b are both positive or one of it is negative (not both of them).
You can write -44 as -1 × 4 × 11 inside square root.
So, (
)
(NOTE : You must know that is written as
)
The line is called the directrix. Here we have a vertical directrix, so a parabola sideways from usual.
Geometry is best done with squared distances. The squared distance from an arbitrary point (x,y) to the vertical line x=2 is
We equate that to the squared distance of (x,y) to the focus (-2,0):
We could call that done. A more standard form might be
