Quadratic Equations

The Quadratic Equations can represent many real-life situations. Now that we know what quadratic equations are, let us learn about the different methods to solve them. Here we will try to develop the Quadratic Equation Formula and other methods of solving the quadratic equations.

The **Standard Form** of a Quadratic Equation looks like this:

For the Quadratic Formula to work, you must have your equation arranged in the form "(quadratic) = 0". Also, the "2a" in the denominator of the Formula is underneath everything above, not just the square root. And it's a "2a" under there, not just a plain "2". Make sure that you are careful not to drop the square root or the "plus/minus" in the middle of your calculations, or I can guarantee that you will forget to "put them back in" on your test, and you'll mess yourself up. Remember that "b^{2}" means "the square of ALL of b, including its sign", so don't leave b^{2} being negative, even if b is negative, because the square of a negative is a positive.
