What is "Completing the Square" in Math? It is the method by which you can rewrite the quadratic equation. E.g., ax 2 + bx + c into a(x - h) 2 +k. To graph the parabola, due to a(x - h) 2 +k, you will know the vertex is at (h, k). Also, if you are finding calculus, then learning how to complete the square may assist you mix a tricky function.

Some quadratic expressions can be factored as perfect squares. For example, x²+6x+9=(x+3)². However, even if an expression isn't a perfect square, we can turn it into one by adding a constant number. For example, x²+6x+5 isn't a perfect square, but if we add 4 we get (x+3)². This, in essence, is the method of *completing the square* Completing the square is a method that represents a quadratic equation as a combination of quadrilateral used to form a square.
