Solution for 0=x^3-kx^2+2kx-k-1 equation:


Simplifying
0 = x3 + -1kx2 + 2kx + -1k + -1

Reorder the terms:
0 = -1 + -1k + 2kx + -1kx2 + x3

Solving
0 = -1 + -1k + 2kx + -1kx2 + x3

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add 'k' to each side of the equation.
0 + k = -1 + -1k + 2kx + -1kx2 + k + x3
Remove the zero:
k = -1 + -1k + 2kx + -1kx2 + k + x3

Reorder the terms:
k = -1 + -1k + k + 2kx + -1kx2 + x3

Combine like terms: -1k + k = 0
k = -1 + 0 + 2kx + -1kx2 + x3
k = -1 + 2kx + -1kx2 + x3

Add '-2kx' to each side of the equation.
k + -2kx = -1 + 2kx + -1kx2 + -2kx + x3

Reorder the terms:
k + -2kx = -1 + 2kx + -2kx + -1kx2 + x3

Combine like terms: 2kx + -2kx = 0
k + -2kx = -1 + 0 + -1kx2 + x3
k + -2kx = -1 + -1kx2 + x3

Add 'kx2' to each side of the equation.
k + -2kx + kx2 = -1 + -1kx2 + kx2 + x3

Combine like terms: -1kx2 + kx2 = 0
k + -2kx + kx2 = -1 + 0 + x3
k + -2kx + kx2 = -1 + x3

Reorder the terms:
1 + k + -2kx + kx2 + -1x3 = -1 + x3 + 1 + -1x3

Reorder the terms:
1 + k + -2kx + kx2 + -1x3 = -1 + 1 + x3 + -1x3

Combine like terms: -1 + 1 = 0
1 + k + -2kx + kx2 + -1x3 = 0 + x3 + -1x3
1 + k + -2kx + kx2 + -1x3 = x3 + -1x3

Combine like terms: x3 + -1x3 = 0
1 + k + -2kx + kx2 + -1x3 = 0
