Need set of point parabola passes through.
X = 1
Y = 8
----------------(1, 8)
For focus,
X2 = 4pY
insert values, solve for p
(1)2 = 4p(8)
= 1/32
=======focus
- 1/32
=======directrix
( long time since I have done this. Formula is correct, check my math )

x=3
What is 5x squared equals 8x?
5x2=8x Divide with x on both sides5x= 8 Solve xx=8/5
What is x squared minus 8x equals negative 12?
If: x^2 -8x = -12 then x^2-8x+12 = 0 and so x = 2 or x = 6
Factor x squared - 8x plus 12 equals 0?
(x - 6)(x - 2)
Factor x squared - 8x plus 15 equals 0?
(x-3)(x-5) = 0
