Solution for (8j+3)(j-2)=0 equation:


Simplifying
(8j + 3)(j + -2) = 0

Reorder the terms:
(3 + 8j)(j + -2) = 0

Reorder the terms:
(3 + 8j)(-2 + j) = 0

Multiply (3 + 8j) * (-2 + j)
(3(-2 + j) + 8j * (-2 + j)) = 0
((-2 * 3 + j * 3) + 8j * (-2 + j)) = 0
((-6 + 3j) + 8j * (-2 + j)) = 0
(-6 + 3j + (-2 * 8j + j * 8j)) = 0
(-6 + 3j + (-16j + 8j2)) = 0

Combine like terms: 3j + -16j = -13j
(-6 + -13j + 8j2) = 0
