Finding c to complete the square
WebFormula for Completing the Square The formula for completing the square for a quadratic, y = 𝑥 2 + b𝑥 + c, is . If y = 𝑥 2 + 6𝑥 + 4, then b = 6 and c = 4. Therefore b / 2 = 3. Therefore becomes . We can simplify 4 – (3) 2 to 4 – 9 which equals -5. The final form of the answer is y = (𝑥 + 3) 2 – 5. WebIt is called completing the square. Here’s how it works. For the polynomial x 2 + b x + c (note here that the coefficient on x 2 is 1) we can complete the square by Find the value of b 2 Square this value to obtain ( b 2) 2 Set this value as c. You will obtain a perfect square trinomial that can be factored as ( x + ( b 2)) 2
