In this math lesson, we learn how to solve quadratic equations using the completing the square method and the quadratic formula. The equation solved in the lesson has a coefficient of x-squared that is not 1, so we learn how to adjust the equation to make it solvable. By completing the square, we get a solution in the form of complex numbers, and when we use the quadratic formula, we get the same solution. This lesson is perfect for anyone looking to improve their skills in solving quadratic equations.
One more example of completing the square to solve a quadratic equation, when the coefficient of x-squared is not 1. The problem is also solved using the quadratic formula.
