Solution for (3+I)(4+2i)= equation:


Simplifying
(3 + I)(4 + 2i) = 0

Multiply (3 + I) * (4 + 2i)
(3(4 + 2i) + I(4 + 2i)) = 0
((4 * 3 + 2i * 3) + I(4 + 2i)) = 0
((12 + 6i) + I(4 + 2i)) = 0
(12 + 6i + (4 * I + 2i * I)) = 0
(12 + 6i + (4I + 2iI)) = 0

Reorder the terms:
(12 + 4I + 6i + 2iI) = 0
(12 + 4I + 6i + 2iI) = 0

4I + 6i + -6i + 2iI = -12 + -6i

Combine like terms: 6i + -6i = 0
4I + 0 + 2iI = -12 + -6i
4I + 2iI = -12 + -6i

Reorder the terms:
12 + 4I + 6i + 2iI = -12 + -6i + 12 + 6i

Reorder the terms:
12 + 4I + 6i + 2iI = -12 + 12 + -6i + 6i

Combine like terms: -12 + 12 = 0
12 + 4I + 6i + 2iI = 0 + -6i + 6i
12 + 4I + 6i + 2iI = -6i + 6i

Combine like terms: -6i + 6i = 0
12 + 4I + 6i + 2iI = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(6 + 2I + 3i + iI) = 0

Ignore the factor 2.
