Frequently Asked Questions

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.

How do you prove the quadratic formula?

The proof is done using the standard form of a quadratic equation and solving the standard form by completing the square. Start with the the standard form of a quadratic equation: ax2 + bx + c = 0. Divide both sides of the equation by a so you can complete the square.

What is the basic quadratic formula?

A quadratic equation is any polynomial equation of degree 2, or any equation in the form , or any equation that can be expressed in that form. The quadratic formula is a formula for solving any quadratic equation by completing the square on the equation , treating a, b, and c as constants.

How do you make a quadratic equation?

Starting with a quadratic equation in standard form, ax2 + bx + c = 0. Divide each side by a, the coefficient of the squared term. Subtract the constant term c/a from both sides. Add the square of one-half of b/a, the coefficient of x, to both sides.
