Assuming you are asking for the Quadratic Formula,
The quadratic equation is often encountered in algebra and arises whenever a problem involves tapping a keg of beer, determining the height of a Frisbee at the end of its flight, or finding the time required for a ballpark vendor to sell all 50 hot dogs he started with if he sells them at a steady rate. The literal meaning of “quadratic” is “pertaining to square,” and as the name suggests, the quadratic equation deals with terms that are squared.
A general quadratic equation has the form
where a, b, and c are real numbers and a ≠ 0. The numbers a, b, and c are the coefficients of the equation, and they determine the nature of the graph of the equation. The number a is called the leading coefficient because it is the coefficient of the x2-term, which is always the first term listed in a quadratic equation written in standard form. The number b is called the middle coefficient because it is the coefficient of the x-term, which is always the middle term listed in a quadratic equation written in standard form. The number c is called the constant term or the terminal coefficient because it is always the last term listed in a quadratic equation written in standard form.
The standard form of a quadratic equation is
where a, b, and c are as defined above and a ≠ 0. Notice that in this form the constant term, c, is always negative. This is not a requirement, but it is often convenient because all the terms are then positive or negative. Notice also that the middle coefficient, b, can be either positive or negative.
The solutions or roots of a quadratic equation are the values of x that make the equation true. In other words, they are the x-intercepts of the graph of the equation. Just as the solutions to linear equations are x-intercepts of the corresponding graph, the solutions to a quadratic equation are x-intercepts of the corresponding graph. Because the graph of a quadratic equation is a curve, it will have either two x-intercepts, one x-intercept, or no x-intercepts.
When a quadratic equation has two solutions, we say that the equation is a

How is 2x2 8x x2-16 solved?
There are a few different ways to solve 2x2 8x x2-16, but one of the simplest is to use the distributive property. This says that for any numbers a, b, and c, a(b+c) = ab+ac. In this case, we can take 2x2 8x and distribute the 2 to both the 8x and the x2-16, giving us 2(8x) + 2(x2-16). This is the same as 16x + 2x2-32, which can be simplified to 2x2 + 14x - 32.
Now that we have our equation in a simpler form, we can solve it using the quadratic equation. This says that for any ax2 + bx + c = 0, the solutions are x = (-b±√b2-4ac)/(2a). In our case, we have a = 2, b = 14, and c = -32, so our equation becomes x = (-14±√142-4(2)(-32))/(2(2)). This simplifies to x = (-14±√196)/4, which means that our two solutions are x = (-14+14)/4 = 0 and x = (-14-14)/4 = -28/4 = -7.
So, the two solutions to 2x2 8x x2-16 are 0 and -7.

What is the difference between 2x2 8x x2-16 and 2x2-8x+x2-16?
There are a few things to consider when looking at the differences between 2x2 8x x2-16 and 2x2-8x+x2-16. To start, 2x2 8x x2-16 can be simplified to 4x2-16, while 2x2-8x+x2-16 can be simplified to 4x2-16 as well. When these equations are simplified, the only difference is the order of the terms. However, this difference is significant when solving the equation.
In general, the order of the terms in an equation will not affect the solution. However, in this case, the order of the terms does impact the solution. The reason for this is that the 2x2 8x x2-16 equation has two squared terms, while 2x2-8x+x2-16 only has one. This means that when solving 2x2 8x x2-16, both the x2 and the 8x terms need to be accounted for. However, when solving 2x2-8x+x2-16, only the x2 term needs to be considered. As a result, the two equations will have different solutions.
2x2 8x x2-16 can be solved by factoring out the 4x2 term. This leaves 4x2-16, which can be further simplified to 0. This means that the solution to 2x2 8x x2-16 is x=4. On the other hand, 2x2-8x+x2-16 can be solved by factoring out the x2 term. This leaves 4x2-16, which can be further simplified to 0. This means that the solution to 2x2-8x+x2-16 is also x=4.
Despite the fact that both equations have the same solution, the process of solving each equation is different. 2x2 8x x2-16 requires the use of both the x2 and 8x terms, while 2x2-8x+x2-16 only requires the use of the x2 term. As a result, the difference between 2x2 8x x2-16 and 2x2-8x+x2-16 is significant.

What is the solution to 2x2-8x
There is no definitive answer to this equation, as it is impossible to determine the value of x without further information. However, there are a few methods that could be used to solve for x.
One approach is to use algebraic methods to solve for x. In this case, one would start by algebraically manipulating the equation to get it into a form that can be solved. For instance, one could add 8x to both sides of the equation, yielding 2x+8x-8x=0. This can be further simplified to 10x=0, and thus x=0.
Another method that could be used to solve this equation is to graph it on a coordinate plane. In this case, one would plot the points corresponding to the equation (2, -8), (4, -16), and so on. Once the points are plotted, one could then draw a line of best fit through the points and solve for the x-intercept, which would give the value of x.
It should be noted that there is no guarantee that either of these methods will give a correct answer, as there may be more than one possible value for x that satisfies the equation. However, these methods can provide a starting point for solving the equation.
