Solution for (3-I)(3+i)= equation:


Simplifying
(3 + -1I)(3 + i) = 0

Multiply (3 + -1I) * (3 + i)
(3(3 + i) + -1I * (3 + i)) = 0
((3 * 3 + i * 3) + -1I * (3 + i)) = 0
((9 + 3i) + -1I * (3 + i)) = 0
(9 + 3i + (3 * -1I + i * -1I)) = 0
(9 + 3i + (-3I + -1iI)) = 0

Reorder the terms:
(9 + -3I + 3i + -1iI) = 0
(9 + -3I + 3i + -1iI) = 0

Solving
9 + -3I + 3i + -1iI = 0

Solving for variable 'I'.

Move all terms containing I to the left, all other terms to the right.

Add '-9' to each side of the equation.
9 + -3I + 3i + -9 + -1iI = 0 + -9

Reorder the terms:
9 + -9 + -3I + 3i + -1iI = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -3I + 3i + -1iI = 0 + -9
-3I + 3i + -1iI = 0 + -9

Combine like terms: 0 + -9 = -9
-3I + 3i + -1iI = -9

Add '-3i' to each side of the equation.
-3I + 3i + -3i + -1iI = -9 + -3i

Combine like terms: 3i + -3i = 0
-3I + 0 + -1iI = -9 + -3i
-3I + -1iI = -9 + -3i

Reorder the terms:
9 + -3I + 3i + -1iI = -9 + -3i + 9 + 3i

Reorder the terms:
9 + -3I + 3i + -1iI = -9 + 9 + -3i + 3i

Combine like terms: -9 + 9 = 0
9 + -3I + 3i + -1iI = 0 + -3i + 3i
9 + -3I + 3i + -1iI = -3i + 3i

Combine like terms: -3i + 3i = 0
9 + -3I + 3i + -1iI = 0
