# Where quadratic equations are used?

## Where quadratic equations are used?

Quadratic equations are commonly used in situations where two things are multiplied together and they both depend on the same variable. For example, when working with area, if both dimensions are written in terms of the same variable, you use a quadratic equation.

## Why are quadratic equations important?

So why are quadratic functions important? Quadratic functions hold a unique position in the school curriculum. They are functions whose values can be easily calculated from input values, so they are a slight advance on linear functions and provide a significant move away from attachment to straight lines.

According to Math Is Fun, real-world examples of the quadratic equation in use can be found in a variety of situations, from throwing a ball to riding a bike. In each example, the predictive qualities of the quadratic equation can be used to assess an outcome.

### How do you calculate quadratic equation?

A quadratic equation is one that can be written out in the form ax2 + bx + c = 0 where a, b and c are whole numbers.

### When do you use the quadratic formula?

The quadratic formula is used when you can’t factor a quadratic equation because it is non-factorable. For example: x^2–5x+3=0 is non factorable, you would have to use the quadratic formula to find the roots. P.S You could also find the roots of an equation by completing the square, or from the graph of the equation itself.
