Solution for (2+4i)(-4-1i)= equation:


Simplifying
(2 + 4i)(-4 + -1i) = 0

Multiply (2 + 4i) * (-4 + -1i)
(2(-4 + -1i) + 4i * (-4 + -1i)) = 0
((-4 * 2 + -1i * 2) + 4i * (-4 + -1i)) = 0
((-8 + -2i) + 4i * (-4 + -1i)) = 0
(-8 + -2i + (-4 * 4i + -1i * 4i)) = 0
(-8 + -2i + (-16i + -4i2)) = 0

Combine like terms: -2i + -16i = -18i
(-8 + -18i + -4i2) = 0

Solving
-8 + -18i + -4i2 = 0

Solving for variable 'i'.

Factor out the Greatest Common Factor (GCF), '-2'.
