Take the Square Root Example: 2x^2=18 Quadratic Formula WebCompleting the square is a process that helps us rewrite a quadratic that's in the form ax 2 + bx + c into the form a (x - h) 2 +k. So, why would we want to do this? Well, for starters, if you want to graph the parabola, a (x - h)2+k is a form that's easier to work with because you automatically know that the vertex is at (h, k).

WebTo put the parabola's equation into vertex form, you have to complete the square. Completing the square just means adding the same number to both sides of the equation -- which, remember, doesn't change the value of the equation -- in order to create a perfect square.
