3 + k + -1kx + -1x + x2 = 0

Solving for variable 'k'.

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

Add '-3' to each side of the equation.
3 + k + -1kx + -1x + -3 + x2 = 0 + -3

Reorder the terms:
3 + -3 + k + -1kx + -1x + x2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + k + -1kx + -1x + x2 = 0 + -3
k + -1kx + -1x + x2 = 0 + -3

Combine like terms: 0 + -3 = -3
k + -1kx + -1x + x2 = -3

Add 'x' to each side of the equation.
k + -1kx + -1x + x + x2 = -3 + x

Combine like terms: -1x + x = 0
k + -1kx + 0 + x2 = -3 + x
k + -1kx + x2 = -3 + x

Add '-1x2' to each side of the equation.
k + -1kx + x2 + -1x2 = -3 + x + -1x2

Combine like terms: x2 + -1x2 = 0
k + -1kx + 0 = -3 + x + -1x2
k + -1kx = -3 + x + -1x2

Reorder the terms:
3 + k + -1kx + -1x + x2 = -3 + x + -1x2 + 3 + -1x + x2

Reorder the terms:
3 + k + -1kx + -1x + x2 = -3 + 3 + x + -1x + -1x2 + x2

Combine like terms: -3 + 3 = 0
3 + k + -1kx + -1x + x2 = 0 + x + -1x + -1x2 + x2
3 + k + -1kx + -1x + x2 = x + -1x + -1x2 + x2

Combine like terms: x + -1x = 0
3 + k + -1kx + -1x + x2 = 0 + -1x2 + x2
3 + k + -1kx + -1x + x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
3 + k + -1kx + -1x + x2 = 0
