Completing the square is a method used to solve a quadratic function. This is a handy method when there are two instances of the same variable in the function.

A quadratic equation.
The quadratic formula is used all the time to solve quadratic equations, often when the factors are fractions or decimals but sometimes as the first choice of solving method. The quadratic formula is sometimes faster than completing the square or any other factoring methods. Quadratic formula find: -x-intercept -where the parabola cross the x-axis -roots -solutions
As one example, the quadratic equation can be used to model many different phenomena - if you were to measure the height of a baseball as it was thrown straight up in the air and pulled down again, and plot the height with respect to time, it would look like a quadratic equation. Computer modelling is a large field with many applications in physics, meterology, and even social sciences.
Do you mean the quadratic formula? Not much; this would be more likely to be used by a scientist or engineer.
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
Quadratic functions are used to describe free fall.

It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.
I'd say no. A quadratic is not linear. It's slope is constantly changing, so there is not one proportion which can be used to predict future values.

If it's a linear function, 3 should do, but 4 will give an extra check on you work. If the function is quadratic exponential, etc. then at least 4 pairs should be used.
Yes.
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.
The quadratic equation is used to find the intercepts of a function (F(x)=x^(2*n), n being an even number) along its primary axis (typically the x axis). Many equations follow this form. The information given by the quadratic equation depends on what your function is pertaining to. If say you have a velocity vs time graph, when the function crosses the xaxis your particle has changed from a positive velocity to a negative velocity. This information can be useful to determine the accompanying behavior of your position. The quadratic equation is simply a tool to find intercepts of a function.
Quadratic is an adjective that is used to describe something that is related to squares. For example, the quadratic equation uses squares, or the second power, and is thus quadratic.
