Solution for (8-i)(6+2i)= equation:


Simplifying
(8 + -1i)(6 + 2i) = 0

Multiply (8 + -1i) * (6 + 2i)
(8(6 + 2i) + -1i * (6 + 2i)) = 0
((6 * 8 + 2i * 8) + -1i * (6 + 2i)) = 0
((48 + 16i) + -1i * (6 + 2i)) = 0
(48 + 16i + (6 * -1i + 2i * -1i)) = 0
(48 + 16i + (-6i + -2i2)) = 0

Combine like terms: 16i + -6i = 10i
(48 + 10i + -2i2) = 0

Solving
48 + 10i + -2i2 = 0
