x3 + x2 - x = 0
∴ x2 + x - 1 = 0
∴ x2 + x + 0.25 = 1.25
∴ (x + 0.5)2 = 1.25
∴ x + 0.5 = ± 1.251/2
∴ x = -0.5 ± 1.251/2

How do you solve x3 plus 125 is equals to 0?
Realising that 125 is a perfect cube, this is actually pretty easy: x3 + 125 = 0 x3 = -125 x = -5
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 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.

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
