x3 + x2 - 8x - 6 = 0
x3 + 3x2 - 2x2 - 6x - 2x - 6 = 0
x2(x + 3) - 2x(x + 3) - 2(x + 3) = 0
(x + 3)(x2 - 2x - 2) = 0
The second bracket cannot be factorised, so applying the quadratic formula to it gives the answers as
So x = -3 or x = 1 +/-sqrt(3)
that is,
x = -3, x = -0.732051 or x = 2.732051

How do you solve X3 equals 216?
cube root of 216 = 6 > X= 6
The curve with equation y2 equals x3 plus 3x2 is called the Tschirnhausen cubic?
y2=x3+3x2
2x3 - 7 plus 5x2 - x3 plus 3x - x3?
2x3 - 7 + 5x - x3 + 3x - x3 = 8x - 7
How do you solve for x if the question is 5x cubed equals 320?
5x3 = 320 x3 = 320/5 = 64 So x = cuberoot(64) = 4
What is x cubed minus 4 x squared plus 7 x divided by x equals?
[ x3 - 4x2 + 7x ] / (x) = x2 - 4x + 7
How do you solve x3 plus 4x2 plus 6x plus 24?
x3 + 4x2 + 6x + 24 = (x2 + 6)(x + 4)
Y equals x3 plus 4x - 3.6?
IMPOSSIBLE
How do you solve X3 equals 216?
cube root of 216 = 6 > X= 6
How do you solve x-1 plus x2-x plus x3-x2 plus x4-x3?
x4 - 1.We can not "solve" this as we have not been told the value of x. However, we can simplify this expression:We have an x and a minus x here which will cancel out. Likewise the x2 and x3 will cancel out with the -x2 and -x3 respectively. This therefore leaves us with just x4 - 1.
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
What is the solution to x3 plus 125 equals 0?
It is x = -5
Is f9x0 equals x3-x2 plus 5 a linear function?
No, it is not.
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)
How do you solve x5 equals 64x2?
x5 = x3 times x2. In this case x3 = 64 so x = cube root of 64 ie 4
How do you factorise x3 plus 2x2-8x plus 5 equals 0?
x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0
How do you find the solutions of x3-12x plus 7?
Since that isn't an equation, there is really nothing to solve.
