Formula for Completing the Square To best understand the formula and logic behind completing the square, look at each example below and you should see the pattern that occurs whenever you square a binomial to produce a perfect square trinomial. f (x) = ax^2 + bx +c f (x) = ax2 + bx +c, completing the square means finding an expression of the form. f ( x) = A ( x − B) 2 + C. f (x) = A (x-B)^2 + C. f (x) = A(x −B)2 +C. Let's consider the case where. a = 1. a = 1 a= 1. For example, for. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation. 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.

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. You can complete the square to rearrange a more complicated quadratic formula or even to solve a quadratic equation. If you want to know how to do it, just follow these steps. That’s just a fancy way of saying that completing the square is a technique that transforms your quadratic equation from an equation that can’t be factored into one that can.

Add the square of half the coefficient of x to both sides. In this case, add the square of half of 6 i.e. add the square of 3. x² + 6x + 9 = −2 + 9 The left-hand side is now the perfect square of (x + 3).
