-2-5
The vertex of the positive parabola turns at point (-2, -11)
x3+3x2+3x+2 divided by x+2 equals x2+x+1
The given equation is y = x - 4x + 2 which can be written as y = -3x + 2 This is an equation of a straight line. Therefore it has no vertex and so cannot be written in vertex form.
It is the average of -2 and +6, that is, x = 2

(xn+2-1)/(x2-1)
The vertex of the positive parabola turns at point (-2, -11)
3 + 2 + 25*3 - 6 = 3 + 2 + 75 - 6 = 74
x3 + 8 = 0, then x3 = -8, therefore x = -2 -2 x -2 = 4 4 x -2 = -8
x3+3x2+3x+2 divided by x+2 equals x2+x+1
(a) y = -3x + 1
Yes.
The given equation is y = x - 4x + 2 which can be written as y = -3x + 2 This is an equation of a straight line. Therefore it has no vertex and so cannot be written in vertex form.
It is the average of -2 and +6, that is, x = 2
y = x + 2 - 4 is the same as y = x - 2 which is the equation of a straight line. A single straight line cannot have a vertex.
x3 - x2 + x - 2 has no rational factors.
