(0-k)(1-k)=0

Solution for (0-k)(1-k)=0 equation:

Simplifying
(0 + -1k)(1 + -1k) = 0
Remove the zero:
(-1k)(1 + -1k) = 0

Remove parenthesis around (-1k)
-1k(1 + -1k) = 0
(1 * -1k + -1k * -1k) = 0
(-1k + 1k2) = 0

Solving
-1k + 1k2 = 0

Solving for variable 'k'.

Subproblem 1
Set the factor 'k' equal to zero and attempt to solve:

Simplifying
k = 0

Solving
k = 0

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

Simplifying
k = 0
Subproblem 2
Set the factor '(-1 + k)' equal to zero and attempt to solve:

Simplifying
-1 + k = 0

Solving
-1 + k = 0

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

Add '1' to each side of the equation.
-1 + 1 + k = 0 + 1

Combine like terms: -1 + 1 = 0
0 + k = 0 + 1
k = 0 + 1

Combine like terms: 0 + 1 = 1
k = 1

Simplifying
k = 1
Solution
k = {0, 1}
