Find positive root of equation x3 equals 2x plus 5?
x^3=2x+5 x^3-2x-5=0 Graph the equation or use a calculator. x= 2.09455148
How many complex roots does 6x4 plus x3 - 5 equals 0 have?
It has two complex roots.
When y is inversely proportial to square of x .K the constant is equals 120 so find x when y is equal to x?
sorry, it is wrong the answer is : y=k/x2(square) {when y = x we will write y as x and leave x2(square) alone. like this: x=120/x2(square) x multiply by x2(square) is x3(cube) so cube root of 120 = x so x is 4.93
How do you find zeros of the function f(x) x3 - 2x 21?
That factors to (x + 3)(x^2 - 3x + 7)Setting those equal to zero leaves one real root (-3) and one complex root: one half times (three minus i times the square root of 19) where i is the square root of negative one.
How do you find a cubic equation with integral coefficients that has the roots 2 and 4 plus i?
If it has integral coefficients and 4+i is a root then its conjugate, 4-i must also be a root. So the equation is f(x) = (x-2)*(x-4-i)*(x-4+i) where each factor is x minus a root. Then multiply these out. = (x-2)*(x2 - 8x + 17) = x3 - 2x2 - 8x2 + 16x + 17x - 34 = x3 - 10x2 + 33x - 34
Square root of x 3?
The square root of x3 is x3/2 or x1.5. Either way it means sqrt(x3).
How do you work out x3 plus 1 equals 65 on calculator?
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
Square root of x to the sixth power?
x3.
What is the square root of x cubed plus x squared?
sqrt(x3 + x2) = x*sqrt(x+1) and that cannot be simplified further.
Y equals x3 plus 4x - 3.6?
IMPOSSIBLE
1 plus x plus x2 plus x3 plus x4 plus plus x24 equals 49x25?
No.
The curve with equation y2 equals x3 plus 3x2 is called the Tschirnhausen cubic?
y2=x3+3x2
Find the multiplicity root of the equation x3-x2-x plus 1 equals 0 near x0 equals 0.9?
The end part of the question does not seem to make sense. The equation has three real roots, a single root at x = -1 and a double root at x = 1
How do you solve X3 equals 216?
cube root of 216 = 6 > X= 6
Is f9x0 equals x3-x2 plus 5 a linear function?
No, it is not.
What is the solution to x3 plus 125 equals 0?
It is x = -5
Write a c plus plus program to find the sum of series S equals 1 plus x2 plus x3 plus x3. plus xn?
(xn+2-1)/(x2-1)
