Solution for (x-(4i))(x-(4i))= equation:


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

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

Multiply -1 * 4
(x + -4i)(x + -1(4i)) = 0

Reorder the terms:
(-4i + x)(x + -1(4i)) = 0

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

Multiply -1 * 4
(-4i + x)(x + -4i) = 0

Reorder the terms:
(-4i + x)(-4i + x) = 0

Multiply (-4i + x) * (-4i + x)
(-4i * (-4i + x) + x(-4i + x)) = 0
((-4i * -4i + x * -4i) + x(-4i + x)) = 0

Reorder the terms:
((-4ix + 16i2) + x(-4i + x)) = 0
((-4ix + 16i2) + x(-4i + x)) = 0
(-4ix + 16i2 + (-4i * x + x * x)) = 0
(-4ix + 16i2 + (-4ix + x2)) = 0

Reorder the terms:
(-4ix + -4ix + 16i2 + x2) = 0

Combine like terms: -4ix + -4ix = -8ix
(-8ix + 16i2 + x2) = 0

Solving
-8ix + 16i2 + x2 = 0

Solving for variable 'i'.

Factor a trinomial.
(4i + -1x)(4i + -1x) = 0

Subproblem 1

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

Subproblem 2

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

Solution

i = {0.25x, 0.25x}
