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 ...
What is the Easiest Way to Learn to complete the Square? The easiest way to learn to complete the square method is using the formula, a(x + m)2+ n = a(x + m)2+ n. Here, m and n can be calculated with the help of the following formulas, m = b/2a and n = c - (b2/4a...
x2−9This is not a perfect square trinomial because it equals(x+3)(x−3). So, what does itreallydo for us? Formulafor 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 ...
