In this lesson on completing the square, you'll learn how to solve quadratic equations. First, you'll learn how to square a binomial, which involves finding the square of the first term and last term, then multiplying the two terms together and doubling them to get the middle term. Then, you'll learn how to use this concept in reverse to solve quadratic equations. By manipulating the equation into a squared form, you can solve for x by taking the square root of both sides and adding or subtracting to find the solutions. This method can be confusing at first, but once you understand it, it will make solving equations much easier.
