- The zeros of a function are the input values which result in an output value of zero.

One way of solving quadratic equations is using factoring
Examples are the following:
1) x2 + 5x + 6 = 0
Set this equal to zero:
(x + 2)(x + 3) = 0
Solve each factor: -2008 All Rights Reserved
x + 2 = 0 or x + 3 = 0
x = –2 or x = – 3
Then, clearly, the zeros are -2 and -3, since those are the input values which will result in an output value of zero.

2) x(x + 5) = 03) x2 – 4 = 0
x = 0 or x + 5 = 0 (x – 2) (x + 2) = 0
x = 0 or x = –5x – 2 = 0 or x + 2 = 0
x = 2 or x = –2

Another way of solving quadratic equations is using quadratic formula

Given, f ( x ) = 2 x2 + 8 x + 1, the zeros are the values of x which result in an output value of y = 0. Thus the zeros are the solutions of the equation
2 x2 + 8 x + 1 = 0

Using the quadratic formula, we get

Another way of solving quadratic equations is using completing the square

...Algebra is a way of working with numbers and signs to answer a mathematical problem (a question using numbers)
As a single word, "algebra" can mean[1]:
* Use of letters and symbols to represent values and their relations, especially for solving equations. This is also called "Elementary algebra". Historically, this was the meaning in pure mathematics too, like seen in "fundamental theorem of algebra", but not now.
* In...

ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which...

The case between Beauty and Stylish involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also...

12. When you flip a light switch, the light seems to come on almost immediately, giving the impression that the electrons in the wiring move very rapidly.
Part A: In reality, the individual electrons in a wire move very slowly through wires. A typical speed for an electron in a battery circuit is 5.0x10 to the -4th meters per second. How long does it take an electron moving at that speed to...

Solving 0 = x5+x-5 using the “Change Of Sign” Method
The method I will use to solve 0 = x5+x-5 is the Change of Sign Method involving the Decimal Search method. I have drawn this graph using the Autograph Software, and the print screen of this is below:
From my graph above, I can see that the root of this equation is between x =1 and x = 1.5. The table of x values and f(x) values is shown...
