Project An Interesting Method for Solving Quadratic Equation from India A quadratic equation can be solved using many different methods availablesuch as quadratic formula, graphical method, factorization, and completing the square. This paper will use and discuss an interesting method for solving quadratic equations came from India (Bluman, 2005).For example, taking quadratic equation . The steps of this method are(a) Move the constant term to the right of the equation.(b) Multiply each term in the equation by four times the coefficient of the term.(c) Square the coefficient of the original x term and add it to both sides of the equation.(d) Take the square root of both sides.(e) Set the left side of the equation equal to the positive square root of the number on the right side and solve for x.(f) Set the left side of the equation equal to the negative square root of the number on the right side and solve for x.

The values x = 2, and x = -5 satisfies the quadratic equation. Therefore, the solutions are correct.Using this approach, the solutions for some other quadratic equations are given below.A) . Solution: , B) . Solution: No real solution, as the right side of the equation is negative number in step (c) of this method (See Appendix 1).C). Solution: , D) . Solution: , In conclusion, whenever it is possible to take square root of the right side of the equation in step (d) of this method, there exist real solutions of the equation.

And, whenever it is not possible to take square root of the right side of the equation in step (d) of this method, there exist no real solutions of the equation.ReferenceBluman, A.G. (2005). Mathematics in Our World. McGraw-Hill: New York.Appendix 1A) B) , no real solution as it is not possible to take square root of -32.C)D) Project #2: Quadratic Formula for Yielding Prime NumbersPrime number is defined as the number divisible by 1 or itself. A prime number has only two factorization 1 and the number itself.

Mathematicians have been searching for a formula that yields prime numbers and found one such formula as (Bluman, 2005). This paper will use this formula for yielding prime numbers and verify extent to which it can generate prime numbers.&nbsp.Let Lets plug in x = 0, 1, 2, 3, 5, 7, 10, 12 and 20 and see if we get prime numbers.(Prime number)(Prime number)(Prime number)(Prime number)(Prime number)(Prime number)(Prime number)(Prime number)(Prime number)Therefore, it can be seen that the yields prime number for smaller values of x.

The formula will not yield prime number when the term will be zero as will be divisible by x. Therefore, putting the term equals to zero.&nbsp.Now, lets plug in x = 41 and 42 and see if we get prime numbers.(Composite number)(Composite number)In conclusion, the formula yields prime number for x value less than 41 (see appendix 1). However, for x value equal to or greater than 41 it does not yields prime number.ReferenceBluman, A.G. (2005). Mathematics in Our World. McGraw-Hill: New York.

• Is there a possibility of plagiarism in my completed order?

We complete each paper from scratch, and in order to make you feel safe regarding its authenticity, we check our content for plagiarism before its delivery. To do that, we use our in-house software, which can find not only copy-pasted fragments, but even paraphrased pieces of text. Unlike popular plagiarism-detection systems, which are used by most universities (e.g. Turnitin.com), we do not report to any public databases—therefore, such checking is safe.

We provide a plagiarism-free guarantee that ensures your paper is always checked for its uniqueness. Please note that it is possible for a writing company to guarantee an absence of plagiarism against open Internet sources and a number of certain databases, but there is no technology (except for turnitin.com itself) that could guarantee no plagiarism against all sources that are indexed by turnitin. If you want to be 100% sure of your paper’s originality, we suggest you check it using the WriteCheck service from turnitin.com and send us the report.
