Example 7. Complete the square: x2 − 7x + ? = (x − ?)2Solution. We will add the square of half of 7, which we write as .x2 − 7x + 49 4 = (x − 72 )2And since the middle term of the trinomial has a minus sign, then the binomial also must have a minus sign...
Your Step-By-Step Guide for How to Complete the Square Now that we’ve determined that our formula can only be solved by completing the square, let’s look at our example formula again: x2+6x=−2 Step 1: Figure Out What’s Missing When you look at the equation above, you can see...
Rewrite the equation, leaving an empty space on the right side of the equation after the "x" term but before the end parenthesis. Divide the coefficient of the "x" term by 2. In y + 10 = 2(x^2 + 4x), divide 4 by 2 to get 2. Square this result. In the example, square 2,...
