### How do you calculate quadratic formula?

The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by: 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.

### Why should i know the quadratic formula?

The quadratic equation is used in the design of almost every product in stores today. The equation is used to determine how safe products are and the life expectancy of products, such as when they can expect to quit working. Designers can then see what needs to be changed in the product to make it last longer.

### What careers use the quadratic formula?
