The complete factoring is: Ignore the factor of 2, since 2 can never be 0. Multiply it all to together to show that it works! We will turn the trinomial into a quadratic with four terms, to be able to do the grouping.

The reason why the father wished to close down the branch was that it appeared to be making a loss. However, it is quite the reverse; if the branch was closed then, the positive contribution from the branch would be lost and overall profits would fall.

This is because the indirect costs of production do not vary with output and, therefore, closure of a section of the firm would not lead to immediate savings. This may mean that closing the branch would be a mistake on financial grounds.

This mistake is made due to a misunderstanding of nature of cost behavior. If the branch is closed then the only costs that would be saved are the costs directly related to the running of the branch: The costs are indirect in nature, in this example the marketing and central administration costs, would still have to be paid as they are unaffected by output.

For this decision to be made, we should use contribution as a guide for deciding whether or not to close a branch. This can also be applied to the production of certain product lines, or the cost effectiveness of departments.

On financial grounds, contribution is therefore, a better guide in making decisions.Each linear equation describes a straight line, and can be expressed using the slope intercept form equation.

As we have seen before, you can write the equation of any line in the form of y = mx + b. This is the so-called slope intercept form, because it gives you two important pieces of information: the slope m and the y-intercept b of the.

Axis of Symmetry in a Parabola. In this lesson, our concern is the symmetry of a parabola in the x-y coordinate plane.. Figure 2 shows a parabola that has an axis of symmetry that lies on the y. Python is a basic calculator out of the box. Here we consider the most basic mathematical operations: addition, subtraction, multiplication, division and exponenetiation.

we use the func:print to get the output. In this lesson, we will define a parabola, discover its everyday uses, determine the functions of the intercept form of the equation, and find the x-intercepts of a parabola. By rearranging a quadratic equation, you can end up with an infinite number of ways to express the same thing.

Learn about the three main forms of a quadratic and the pros and cons of each. The vertex form of a parabola's equation is generally expressed as: y = a(x-h) 2 +k (h,k) is the vertex as you can see in the picture below. If a is positive then the parabola opens upwards like a regular "U". If a is negative, then the graph opens downwards like an upside down "U".
