Does y equals 3x2 minus 5x plus 1 cross the x axis?
Yes, it crosses at (0.23,0) and (1.43,0).
3x2 plus 3x minus 60?
the answer is -174
What is the line of symmetry and the vertex when y equals 3x squared plus 2x minus 1?
y = 3x2+2x-1 Line of symmetry: x = -1/3 Vertex coordinate: (-1/3, -4/3)
How many times does 3x2 plus 8x plus 5 touch or cross the x axis?
If you mean: 3x2+8+5 = 0 Then it crosses the x axis at points -1 and -5/3
What is the line of symmetry for the graph of y equals -3x2 plus 12x - 11?

Quotient and remainder of 3X4 plus 2X3 minus X2 minus x minus 6 divided by X2 plus 1?
(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).
Factor 3x to the third power minus 3x to the second power plus 2x minus 2?
3x3 - 3x2 + 2x - 2 = 3x2(x - 1) + 2(x - 1) = (3x2 + 2)(x - 1)
What is the factored form of 3x2 plus 21x minus 24?
3(x - 1)( x + 8)
What is the name of this function 4y plus 8 equal to 3x to the power of 2 minus 2x plus 1?
if you rearrange it, it becomes 4y + 8 = 3x2 -2x +1 4y = 3x2 -2x -7 y= (3x2 -2x -7)/4 which is a parabola
What is the line of symmetry for the parabola whose equation is y equals 3x2 plus 24x - 1?
Vertical line of symmetry cuts through x = -4 - (sqrt of 3)
