a quadratic equation is used to
When would we use the quadratic formula?
When would I use the Quadratic Formula? You can use the Quadratic Formula any time you're trying to solve a quadratic equation — as long as that equation is in the form "(a quadratic expression) that is set equal to zero".
Not all quadratic equations have two solutions, and the notion of dependent vs. independent variable would not be self-evident from looking at a quadratic equation in two variables.
The short answer: no equation is a function.
Where is quadratic equations used in real life?
For a parabolic mirror, a reflecting telescope or a satellite dish, the shape is defined by a quadratic equation.
Quadratic equations are also needed when studying lenses and curved mirrors.
And many questions involving time, distance and speed need quadratic equations.
What is the role of the quadratic equation?
The quadratic formula helps us solve any quadratic equation.
First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients.
Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .
See examples of using the formula to solve a variety of equations.
