Quadratic functions are used all the time, every day, all over the world. Even though right now, it doesn’t seem like this kind of math is ever going to creep back into our life. That is actually far from true. These math skill are crucial to have if one ever decides to do anything in engineering, or something like that. Those types of jobs are now becoming more and more popular, because the world is always going to need educated people who know how to construct or refurbish buildings and homes.

Sky scrapers are not easy types of building to build. Unlike children’s toy blocks, skyscrapers have to be able to withstand immense weather conditions, or else, like children’s blocks, the skyscraper would raze down to the ground. Skyscrapers call for an extensive amount of planning, and skill. First of all, each skyscraper is deigned much differently. They are different depending on climate, and usual weather conditions. For example, the structure of a building in Dubai is going to be much different from one in Alaska. Math is involved by using quadrics. Things that need to be considered are pressure vs. wind velocity. That means that the engineers need to take into consideration how much pressure is needed to withstand how much wind is going to be pushing the building.

Quadratic functions are actually used in NASA. NASA uses those functions to launch their spaceships into space. There is obviously a lot of planning and smarts that have to go into rocket science. The scientists have to take so much into consideration. Like not blowing something/someone up on accident, weight, height, velocity, wind..the list goes on and on. A way that quadratics relate to all of this is by using the parabola. It shows the rocket scientists the highest power term in the equation. An example of a quadratic that is a parabola is: x = c + b * x + a * x^2. That equation shows the distance that something will move vertically when rising against gravity. Obviously important for launching a...

...• A quadraticfunction (f) is a function that has the form as f(x) = ax2 + bx + c where a, b and c are real numbers and a not equal to zero (or a ≠ 0). • The graph of the quadraticfunction is called a parabola. It is a "U" or “n” shaped curve that may open up or down depending on the sign of coefficient a. Any equation that has 2 as the largest exponent of x is a quadraticfunction.

...A quadratic equation is an equation that has a second-degree term and no higher terms. A second-degree term is a variable raised to the second power, like x2. When you graph a quadratic equation, you get a parabola, and the solutions to the quadratic equation represent where the parabola crosses the x-axis.
A quadratic equation can be written in the form:
quadratic equation,
where a, b, and c are numbers (a ≠0), and...

...Quadratic Equation:
Quadratic equations have many applications in the arts and sciences, business, economics, medicine and engineering. Quadratic Equation is a second-order polynomial equation in a single variable x.
A general quadratic equation is:
ax2 + bx + c = 0,
Where,
x is an unknown variable
a, b, and c are constants (Not equal to zero)
Special Forms:
* x² = n if n < 0, then x has no real value
* x² = n if...

1. Quadratic Equation
If p(x) is a quadratic polynomial, then p(x) = 0 is called
a quadratic equation. The general formula of a quadratic
equation is ax 2 + bx + c = 0; where a, b, c are real
numbers and a 0. For example, x2 – 6x + 4 = 0 is a
quadratic equation.
