5x2 + x - 4 = 0
a = 5, b = 1, c = -4
The equation of the axis of the symmetry of a parabola is x = - b/2a, which also is the x-coordinate of the vertex.
x = - b/2a = - 1/2
Find the y-coordinate:
f(x) = 5x2 + x - 4
f(-1/2) = 5(-1/2)2 + (-1/2) - 4 = 5(1/4) - 1/2 - 4 = 5/4 - 1/2 - 4 = 4/2 - 4 = 2 - 4 = -2
Thus, the vertex is (-1/2, -2).

What answer is equal to the sum in the expression below (3x3 plus 4x2 - 2x plus 1) plus (x4 - x3 plus 5x2 plus 2x plus 3)?
Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
What is the derivative of x to the fourth power -3x cubed plus 5x2 divided by x squared?
If you mean: f(x) = x4 - 3x3 + 5x2 / x2 then: f(x) = x4 - 3x3 + 5 ∴ f'(x) = 4x3 - 9x2 If you mean: f(x) = (x4 - 3x3 + 5x2) / x2 then: f(x) = x2 - 3x + 5 ∴ f'(x) = 2x - 3
1 plus x plus x2 plus x3 plus x4 plus plus x24 equals 49x25?
No.
X4 plus 7x2 minus 60 factor completely?
x4 + 7x2 - 60 = x4 + 12x2 - 5x2 - 60 = x2(x2 + 12) - 5(x2 +12) = (x2 - 5)(x2 +12)
What is the remainder when the polynomial x4 5x2 10x 12 is divided by x plus 2?
I assume you meant x^4 + 5x^2 +10x + 12. The remainder is 28

X4 equals 2x3 plus 1?
Not necessarily.
Is this odd even or neither 5x2 plus x4?
If the "x" in "x4" was a typing mistake, then 14 is even. If the "x" means "times" then your question makes no sense. If "x4" means "x to the 4th power" then your question can not be answered without knowing the value of x
1 plus x plus x2 plus x3 plus x4 plus plus x24 equals 49x25?
No.
X4 plus 7x2 minus 60 factor completely?
x4 + 7x2 - 60 = x4 + 12x2 - 5x2 - 60 = x2(x2 + 12) - 5(x2 +12) = (x2 - 5)(x2 +12)

I assume you meant x^4 + 5x^2 +10x + 12. The remainder is 28
X4 plus x2 equals 1?
4X + 2x = 1. Where x = 0.166666666666666666666666666666666666666 recurring.
What is 7 x4 equals?
28 is.
What is x4-144 equals 0?
7
Is 9 x4 equals 36?
yes
How do you express x4 plus y4 if given x plus y equals a xy equals b?
(x + y)2 = x2 + 2xy + y2 So x2 + y2 = (x + y)2 - 2xy = a2 - 2b Then (x2 + y2)2 = x4 + 2x2y2 + y4 So x4 + y4 = (x2 + y2)2 - 2x2y2 = (a2 - 2b)2 - 2b2 = a4 - 4a2b + 4b2 - 2b2 = a4 - 4a2b + 2b2
