-2i(4-2i)=

Solution for -2i(4-2i)= equation:

Simplifying
-2i(4 + -2i) = 0
(4 * -2i + -2i * -2i) = 0
(-8i + 4i2) = 0

Solving
-8i + 4i2 = 0

Solving for variable 'i'.

Factor out the Greatest Common Factor (GCF), '4i'.

Ignore the factor 4.
Subproblem 1
Set the factor 'i' equal to zero and attempt to solve:

Simplifying
i = 0

Solving
i = 0

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

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

Simplifying
-2 + i = 0

Solving
-2 + i = 0

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

Add '2' to each side of the equation.
-2 + 2 + i = 0 + 2

Combine like terms: -2 + 2 = 0
0 + i = 0 + 2
i = 0 + 2

Combine like terms: 0 + 2 = 2
i = 2

Simplifying
i = 2
Solution
i = {0, 2}
