The two numbers are -5 and -4 Explanation: Assume that the first number is x and that the second number is x+1. We know that the sum of their squares is This means that: x² + (x+1)² = 41 We will expand the brackets and factorize to get the value of x as follows: x² + (x+1)² = 41 x² + x² + 2x + 1 = 41 2x² + 2x + 1 - 41 = 0 2x² + 2x.   2 (x^2 + x - 72) = 0 Now, assuming you know how to factor a quadratic, we look for two numbers that multiply to get and add to get 1. 9 and -8 come to mind because (9)(-8) = and -8 + 9 = 1. So we write, 2 (x + 9)(x - 8) This means we have two possible answers when we equate the terms inside the bracket to 0 and solve for x.

The sum of the squares of two consecutive odd positive integers is Find the numbers. Find the sum of the squares of the integers from 1 to MySquare, where MySquare is input by the user. Be sure to check that the User enters a positive integer. Use the top-down modular approach and pseudocode. Validate the input data.

Number Theory has fascinated mathematicians from the most ancient of times. A remarkable feature of number theory is the fact that there is something in it for everyone from puzzle enthusiasts, problem solvers and amatcur mathematicians to professional scientists and .   I am just going to assume you are looking for "positive" consecutive integers, and they would be 11 and 12 although and ( + 1) would work just as well. 0 0 0 Login to reply the answers Post.

### On the representation of --1 as a sum of two squares of cyclotomic integers by P. Chowla Download PDF EPUB FB2

It seems to be very well known that $33$ is the largest integer with zero representations as a sum of five nonzero squares. So it seems reasonable to me that as we go higher and higher, numbers have more and more representations as sums of five nonzero squares, and maybe there is a threshold above which all numbers have at least two such representations.

The sum of squares of two consecutive positive integers is sixty-one. Find the two integers.: Let the first integer be, x Then the next consecutive integer is, x+1 Square means raise it to the second power and sum means, + set each factor = to 0 and solve if possible: 2=0 (not possible) x+6=0 x+= x=-6 (ignore because we onlywant the.

Some Conjectures About Cyclotomic Integers By Raphael M. Robinson 1. Introduction. Kronecker  proved in that the only algebraic integers which lie with their conjugates on the unit circle | z \ = 1 are the roots of unity.

If we consider instead the closed interior of the unit circle, \. ON THE REPRESENTATION OF A NUMBER AS THE SUM OF ANY NUMBER OF SQUARES, AND IN PARTICULAR OF FIVE* BY G. HARDY 1. Introduction 1. In a short note published recently in the Proceedings of the National Academy of Sciences1 I sketched the outlines of a new solution of one of the most interesting and difficult problems in the.

$\begingroup$ Just noting that $(a^2+b^2)(c^2+d^2)=(ac+bd)^2+(ad-bc)^2=(ac-bd)^2+(ad+bc)^2$ states that if a number is the product of two sums of squares,then the number can also be written as the sum of two is the sum of squares identity of Diophantus.

Click here to see ALL problems on Problems-with-consecutive-odd-even-integers Question the sum of the square of the two consecutive odd intergers is equal to find the two intergers Found 2 solutions by Fombitz, jojo   I am uncertain who came up with this beautiful proof, but here it is: From this it is easy to derive the formula $n(n + 1)(2n + 1)/6$.

@Chan: IIRC we wrote p == 1 (mod 4) at my uni, which probably also makes things easier for non-mathematicians to read. Where == is the best ascii representation of what we actually wrote, which was an ≡ character when it was necessary to be pedantic, or just = if it's obvious and you're lazy.

Or if you've formally declared that you're working entirely in the ring of integers. Therefore it is false that every totally positive algebraic integer in a number field is a sum of 4 squares (or even any number of squares) of algebraic integers. Here are some further examples: In $\mathbf{Q}(\sqrt{2})$, $5 + 3\sqrt{2}$ is totally positive since $5+3\sqrt{2}$ and $\sqrt{2}$ are both positive.

In additive number theory, Fermat's theorem on sums of two squares states that an odd prime p can be expressed as: = +, with x and y integers, if and only if ≡ (). The prime numbers for which this is true are called Pythagorean example, the primes 5, 13, 17, 29, 37 and 41 are all congruent to 1 modulo 4, and they can be expressed as sums of two squares in the following.

Every positive integer is a sum of four integer squares. by Michael Barr. Introduction. The theorem of the title has been known for centuries, perhaps longer, but I believe that Lagrange gave the first proof.

When I was a student, I saw a very different (and. It is shown that the set of prime integers in Q(p 2) is partitioned into two sets with respect to their representation as a sum of squares: 1) a set S0 of primes that cannot be represented as a Author: Michele Elia.

Properties. A cyclotomic field is the splitting field of the cyclotomic polynomial = ∏ (,) = ≤ ≤ (−)and therefore it is a Galois extension of the field of rational numbers.

The degree of the extension [Q(ζ n):Q]is given by φ(n) where φ is Euler's phi function.A complete set of Galois conjugates is given by { (ζ n) a }, where a runs over the set of invertible residues modulo n (so.

The sum of the squares of two consecutive negative odd integers is equal to How do you find the two integers. Algebra Quadratic Equations and Functions Linear, Exponential, and Quadratic Models. In a recent work, S. Cooper (J. Number Theory –,) conjectured a formula for r 2k+1 (p 2), the number of ways p 2 can be expressed as a sum of 2k+1 squares.

Inspired by this conjecture, we obtain an explicit formula for r 2k+1 (n 2),n≥ by: 4. Sum of Two Squares Date: 12/04/97 at From: Mary Writz Subject: Sum of two squares Here is a problem we have been working on in my math class.

The number 65 can be expressed as the sum of two squares in two different ways: 65 = 8'2 + 1'2 = 7'2 + 4'2. An elementary manipulation shows that the residue of the Dedekind zeta function at s = 1 is the average of the coefficients of the Dirichlet series representation of the Dedekind zeta function.

The n -th coefficient of the Dirichlet series is essentially the number of representations of n as a sum of two squares of nonnegative integers. Melissa L. asked • 12/09/15 The sum of the squares of two consecutive positive integers is Find the integers. The sum of the squares of two consecutive integers is 9 greater than 8 times the smaller integer (Algebra 1) The sum of the squares of two consecutive integers is 9.
