How do you complete the square for dummies?
Completing the square involves creating a perfect square trinomial from the quadratic equation, and then solving that trinomial by taking its square root. Put the x-squared and the x terms on one side and the constant on the other side. Divide both sides by the coefficient of x-squared (unless, of course, it’s 1).
What is completing the square in math?
Completing the square means writing a quadratic in the form of a squared bracket and adding a constant if necessary. For example, consider x2 + 6x + 7. Start by noting that. (x + 3)2 = (x + 3)(x + 3) = x2 + 6x + 9.
