Completing the square formula is a technique or method to convert a quadraticpolynomialor equation into aperfect squarewith some additional constant. A quadratic expression in variable x: ax2+ bx + c, where a, b and c are any real numbers but a ≠ 0, can be converted into a perfect squ...
To complete the square, take the value of b from the standard form of the quadratic function and plug it into the completing the square formula to produce a perfect square trinomial. Afterward, simplify the perfect square trinomial to successfully transform the function into the vertex form of ...

Proof of the quadratic formulaTo prove the quadratic formula, we complete the square. But to do that, the coefficient of x2 must be 1. Therefore, we will divide both sides of the original equation by a:on multiplying both c and a by 4a, thus making the denominators the same (Lesson ...
