(6-4i)(4-2i)=

Solution for (6-4i)(4-2i)= equation:

Simplifying
(6 + -4i)(4 + -2i) = 0

Multiply (6 + -4i) * (4 + -2i)
(6(4 + -2i) + -4i * (4 + -2i)) = 0
((4 * 6 + -2i * 6) + -4i * (4 + -2i)) = 0
((24 + -12i) + -4i * (4 + -2i)) = 0
(24 + -12i + (4 * -4i + -2i * -4i)) = 0
(24 + -12i + (-16i + 8i2)) = 0

Combine like terms: -12i + -16i = -28i
(24 + -28i + 8i2) = 0

Solving
24 + -28i + 8i2 = 0

Solving for variable 'i'.
