Yes, it crosses at (0.23,0) and (1.43,0).
the answer is -174
y = 3x2+2x-1 Line of symmetry: x = -1/3 Vertex coordinate: (-1/3, -4/3)
If you mean: 3x2+8+5 = 0 Then it crosses the x axis at points -1 and -5/3
-2

That depends on whether or not 2x is a plus or a minus

(3x4 + 2x3 - x2 - x - 6)/(x2 + 1)= 3x2 + 2x - 4 + (-3x - 2)/(x2 + 1)= 3x2 + 2x - 4 - (3x + 2)/(x2 + 1)where the quotient is 3x2 + 2x - 4 and the remainder is -(3x + 2).
3x3 - 3x2 + 2x - 2 = 3x2(x - 1) + 2(x - 1) = (3x2 + 2)(x - 1)
3(x - 1)( x + 8)
if you rearrange it, it becomes 4y + 8 = 3x2 -2x +1 4y = 3x2 -2x -7 y= (3x2 -2x -7)/4 which is a parabola
Vertical line of symmetry cuts through x = -4 - (sqrt of 3)
