Remove parenthesis around (2i)
2i(4i) = 0
Remove parenthesis around (4i)
2i * 4i = 0
Reorder the terms for easier multiplication:
2 * 4i * i = 0
Multiply 2 * 4
8i * i = 0
Multiply i * i
8i2 = 0
Solving
8i2 = 0
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Divide each side by '8'.
i2 = 0
Simplifying
i2 = 0
Take the square root of each side:
i = {0}
