y2 = -x2 - 8x + 6
The one which says: y2 = 4 - 4/25 x2
y^2=-x^2-8x+6
If you mean: y2+5y+6 then it is (y+2)(y+3) when factored completely
4 - y2 can be written as 22 - y2. This has become of the form of x2 - y2.Expansion for x2 - y2 is (x+y)(x-y).So, 4 - y2 = 22 - y2 = (2+y)(2-y)

No, any equation of the form x2+y2=r2, with r as any number, makes a circle centered at the origin with radius r. Hyperbolas can be of the form xy=k or x2-y2=r2.
y2 - 64 can be written as y2 - 82, which is of the form of a2 - b2.And a2 - b2 is factored as (a-b)(a+b).Therefore, y2 - 64 is factored as (y+8)(y-8).
A formula that shows you how to do or solve a mathematical problem. Ex. Y2-Y1 ------- X2-X1 That is used to find the slope of two points (Also known as point form, if I am correct.)
2(x - y)(x + y)(x2 - xy + y2)(x2 + xy + y2)
The component form of a vector AB would typically be represented as (x2 - x1, y2 - y1), where A is at the point (x1, y1) and B is at the point (x2, y2).
two points form a line. (x1,y1)(x2,y2)
Equations of circles are usually in x2+y2=(radius)2 form, so if you have x2 + y2 = 25 x2 + y2 = 52 then radius = 5.
