Answer: (x-9)(x+1), so x=9 and x=-1
Step-by-step explanation:
X^2-8x-9=0
-9 times 1 = -9 and -9 plus 1 = -8
So (x-9)(x+1)
X=9, x=-1

Step-by-step explanation:
Answer:
circumference
Step-by-step explanation:
it's a circle
The standard equation is 4p(x-h) = (y-k)^2 where |p| = focal distance |4p| = focal width.
<span>x=-1/8y^2
-8x=y^2
4*(-2)(x-0) =( y-0)^2
p = -2, h=0, k=0</span><span>
focal width = |4*(-2)| = 8
The answer to your question is that the length of the focal width is equal to 8.</span>
