Solving the Equation (x - 5i)(x + 5i) = 0
This equation represents a simple quadratic equation with complex coefficients. Let's break down how to solve it:
Understanding Complex Numbers
Before we dive into the solution, let's remember that complex numbers are numbers that can be expressed in the form a + bi, where 'a' and 'b' are real numbers, and 'i' is the imaginary unit, defined as the square root of -1 (i² = -1).
Solving the Equation
-
Zero Product Property: The equation (x - 5i)(x + 5i) = 0 utilizes the Zero Product Property, which states that if the product of two or more factors is zero, then at least one of the factors must be zero.
-
Setting Factors to Zero: Therefore, to solve the equation, we set each factor equal to zero:
- x - 5i = 0
- x + 5i = 0
-
Solving for x: Solving for 'x' in each equation, we get:
- x = 5i
- x = -5i
Solution
Therefore, the solutions to the equation (x - 5i)(x + 5i) = 0 are x = 5i and x = -5i.
Note
The solutions are complex conjugates of each other. This is a common pattern when dealing with quadratic equations involving complex numbers.
