In Completing the Square 3, the teacher shows how to complete the square to solve quadratic equations, with a focus on more difficult problems. The method involves putting the x-squared and x-term on one side of the equation and the constant on the other, then finding the perfect square that would make the equation balance. Using the square root property, the teacher then shows how to solve for both real and imaginary solutions. The lesson also previews the next installment, which will cover quadratics with coefficients other than 1.
