First rewrite the quadratic equation in the form: ax2 + bx + c = 0 where a , b and c are constant coefficients. Clearly, a is not = 0 for if it were then you would have a linear equation and not a quadratic.
Then the roots of the quadratic are:
x = [-b +/- sqrt(b2 - 4ac)]/2a
where using the + and - values of the square root result in two solutions.

What is an application for a quadratic equation in real life?
A quadratic equation could be used to find the optimal ingredients for a mixture. Example: if you are trying to create a super cleanser, you could make a parabola of your ingredients, finding the roots of the equation to find the optimal amount for each ingredient.
What are some examples of quadratic equation?
x to the power of a whole number, like y=x to the power of 3 or y= x to the power of 6, that will create a parabola
How can you decide what graph equation and function type?
Create a scatter plot. That might give some indication of the function type. Try out different function. Once you get experience it will come easier.
Can you create a quadratic equation with the solution being -5?
Yes, this can be done this way:(x-(-5))(x+a)=0, where a is any (positive or negative) numberThis simplifies to: (x+5)(x+a) = 0or written as quadratic: x2+(a+5)x+5a = 0Solutions: x1 = -5 and x2 = -a,so if a=5 the equation shortens to (x+5)2=0 ( or x2+10x+25=0 )and there will be only one solution: x1,2 = -5
If you have a point on a line what else is needed in order to create an equation?
If a point on a line is already known, what else is needed in order to create an equation
How is the St. Louis Arch an example of a Quadratic Function?
The St. Louis Arch is in the shape of a hyperbolic cosine function It is often thought that it is in the shape of a parabola, which would have a quadratic function of y = a(x-h)^2 + k, where the vertex is h, k.

Given a number. square it. then subtract the sum of twice the number and 4 The result is zero. Find the number?
You want to create an equation for this. The equation should look like this: x^2 - 2x + 4 = 0 Use the quadratic equation to solve it.

Why is force needed?
Force happens when an object of mass is accelerated, and the equation to calculate force is : force=mass/acceleration
How can you insert a quadratic formula in your document on Microsoft word?
To insert a quadratic formula (or any other scientific formula) into a Word document, go toInsert (tab) > Equations (under the Symbols block)From there you can either select the format of the formula you would like to insert if a template is available (there is a template already for quadratic equations) but if there isn't one, can either download on from Office.com OR create your own by clicking Insert New Equation.
