Channel 4 Learning, originally part of Channel 4, was created to produce support materials that motivate and inspire learners aged 4–19 while empowering teachers to create engaging lessons. Primary resources cover Early Years, Key Stage 1 and Key Stage 2. Secondary resources cover Key Stage 3, Key Stage 4 and GCSEs.
Squares are always congruent to 0, 1, 4, 5, 9, 16 modulo 20. The values repeat with each increase of a by 10. In this example, N is 17 mod 20, so subtracting 17 mod 20 (or adding 3), produces 3, 4, 7, 8, 12, and 19 modulo 20 for these values. It is apparent that only the 4 from this list can be a square.
In mathematics, factorization (or factorisation, see English spelling differences) or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind. For example, 3 × 5 is an integer factorization of 15, and (x – 2)(x + 2) is a polynomial ...
If two or more factors of a polynomial are identical, then the polynomial is a multiple of the square of this factor. The multiple factor is also a factor of the polynomial's derivative (with respect to any of the variables, if several). For univariate polynomials, multiple factors are equivalent to multiple roots (over a suitable extension field).
The theory of finite fields, whose origins can be traced back to the works of Gauss and Galois, has played a part in various branches of mathematics.Due to the applicability of the concept in other topics of mathematics and sciences like computer science there has been a resurgence of interest in finite fields and this is partly due to important applications in coding theory and cryptography.
In number theory, the continued fraction factorization method (CFRAC) is an integer factorization algorithm.It is a general-purpose algorithm, meaning that it is suitable for factoring any integer n, not depending on special form or properties.

[1] [2] Sometimes the factor's charges paid by the seller (the factor's "client") covers a discount fee, additional credit risk the factor must assume, and other services provided. [13] The factor's overall profit is the difference between the price it paid for the invoice and the money received from the debtor, less the amount lost due to non ...
