Algebra: Quadratic Equations

A quadratic equation is an equation that has a second-degree term and no higher terms. A second-degree term is a variable raised to the second power, like x 2.When you graph a quadratic equation, you get a parabola, and the solutions to the quadratic equation represent where the …

Quadratic Formula

You can use this formula to solve quadratic equations. Or, if your equation factored, then you can use the quadratic formula to test if your solutions of the quadratic equation are correct. The expression b 2 – 4 a c, which is under the (sqrt) inside the quadratic formula is called the discriminant.

Solve a Quadratic Equation in Excel

Quadratic Equation 1. For example, we have the formula y = 3x 2 – 12x + 9.5. It’s easy to calculate y for any given x. For x = 1, y = 0.5 2. For x = 2, y = -2.5 3. But what if we want to know x for any given y? For example, y = 24.5. We need to solve 3x 2 – 12x + 9.5 = 24.5. We 4. You can use
