Solution for (2i)(1-4i)(1+i)=0 equation:


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

Remove parenthesis around (2i)
2i(1 + -4i)(1 + i) = 0

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

Combine like terms: 1i + -4i = -3i
2i(1 + -3i + -4i2) = 0
(1 * 2i + -3i * 2i + -4i2 * 2i) = 0
(2i + -6i2 + -8i3) = 0

Solving
2i + -6i2 + -8i3 = 0

Solving for variable 'i'.

Factor out the Greatest Common Factor (GCF), '2i'.
2i(1 + -3i + -4i2) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'i' equal to zero and attempt to solve: Simplifying i = 0 Solving i = 0 Move all terms containing i to the left, all other terms to the right. Simplifying i = 0

Subproblem 2

Set the factor '(1 + -4i)' equal to zero and attempt to solve: Simplifying 1 + -4i = 0 Solving 1 + -4i = 0 Move all terms containing i to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -4i = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -4i = 0 + -1 -4i = 0 + -1 Combine like terms: 0 + -1 = -1 -4i = -1 Divide each side by '-4'. i = 0.25 Simplifying i = 0.25

Subproblem 3

Set the factor '(1 + i)' equal to zero and attempt to solve: Simplifying 1 + i = 0 Solving 1 + i = 0 Move all terms containing i to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + i = 0 + -1 Combine like terms: 1 + -1 = 0 0 + i = 0 + -1 i = 0 + -1 Combine like terms: 0 + -1 = -1 i = -1 Simplifying i = -1

Solution

i = {0, 0.25, -1}
