How do you create a function to calculate the roots of any given quadratic equation?
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

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.

What is Factor-Factorproduct relationship?
The Factor-Factor Product Relationship is a concept in algebra that relates the factors of a quadratic equation to the roots or solutions of the equation. It states that if a quadratic equation can be factored into the form (x - a)(x - b), then the roots of the equation are the values of 'a' and 'b'. This relationship is crucial in solving quadratic equations and understanding the behavior of their roots.

How can I calculate a double integral using the trapz function in MATLAB?
To calculate a double integral using the trapz function in MATLAB, you can first create a grid of points for the two variables you are integrating over. Then, evaluate the function you are integrating at these points to create a matrix of function values. Finally, use the trapz function twice - once along one dimension and then along the other dimension - to compute the double integral.
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.

What can you not create using a word processing application?
A spreadsheet. Spreadsheets usually rely on formulae to calculate numbers. That function is not part of a word-processor.
