Solving an equation by using the square root property - Math help

The video tutorial explains how to solve an equation using the square root property. It begins by isolating the variable through subtraction, then applies the square root to both sides of the equation. The tutorial addresses the issue of taking square roots of negative numbers, introducing the concept of complex numbers and the imaginary unit 'i'. Finally, it demonstrates how to write the solution in standard form, emphasizing the importance of including both the plus and minus signs and the imaginary unit.
