Quadratic functions will be used in chemistry in real life. Quadratic equations are used to solve equilibrium problems and determine the amount of reactants in a mixture that will react and the concentrations of products that will be form.
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
Calculating the path of an object when acted on by a continual force (like a ball thrown where there is gravity)
Equations using multiple variables, or powers of variables, may not provide a simple numerical value for a given variable. Equations that are solvable using the quadratic formula may result in two values.
quadratics are used for things like satellite dishes... there are more uses but that's only a basic one =) we are doing a project in math that requires quadratic equations. we make a parabola and put aluminum (or any other reflector) inside the parabola. we make a stick to put in the middle of the parabola to make a focus. we put the marshmellow on the focus and put the parabola in the sunlight. If done right then the marshmellow should heat up! cool huh?
