Completing square to find vertex form
WebThe word quadratic refers to the degree of a polynomial such as x² - 4x + 3. To be quadratic, the highest power of any term must be 2 (the x is squared). If there is no equals sign, but it has a quadratic term, then it is a quadratic expression. x² - x - 5 is a quadratic expression. So are the following: a² + 8a - 6. WebWhat is completing the square? Completing the square is a technique for rewriting quadratics in the form (x+a)^2+b (x +a)2 +b. For example, x^2+2x+3 x2 +2x +3 can be rewritten as (x+1)^2+2 (x +1)2 +2. The two expressions are totally equivalent, but the …
