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. WebDerivation of Quadratic Formula. A Quadratic Equation looks like this: And it can be solved using the Quadratic Formula: That formula looks like magic, but you can follow …
