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 ...
For example, if n = 171 × p × q where p < q are very large primes, trial division will quickly produce the factors 3 and 19 but will take p divisions to find the next factor. As a contrasting example, if n is the product of the primes 13729, 1372933, and 18848997161, where 13729 × 1372933 = 18848997157, Fermat's factorization method will ...
The formula for the difference of two squares can be used for factoring polynomials that contain the square of a first quantity minus the square of a second quantity. For example, the polynomial x 4 − 1 {\displaystyle x^{4}-1} can be factored as follows:
The entry 4+2i = −i(1+i) 2 (2+i), for example, could also be written as 4+2i= (1+i) 2 (1−2i). The entries in the table resolve this ambiguity by the following convention: the factors are primes in the right complex half plane with absolute value of the real part larger than or equal to the absolute value of the imaginary part.
For example, to factor =, the first try for a is the square root of 5959 rounded up to the next integer, which is 78. Then b 2 = 78 2 − 5959 = 125 {\displaystyle b^{2}=78^{2}-5959=125} . Since 125 is not a square, a second try is made by increasing the value of a by 1.
For example, it will cost you $25,000 to borrow $50,000 at a 1.50 factor rate ($50,000 x 1.5 = $75,000). What is a 1.35 factor rate? A 1.35 factor rate is a mid-range rate lenders charge to borrow ...
For example, the number of irreducible factors of a polynomial is the nullity of its Ruppert matrix. [7] Thus the multiplicities m 1 , … , m k {\displaystyle m_{1},\ldots ,m_{k}} can be identified by square-free factorization via numerical GCD computation and rank-revealing on Ruppert matrices.
For example, if the factoring fee is 2 percent and the invoice amount is $10,000, the charge would be $200. Bankrate insight. Some factoring fees are based on tiered rates. For instance, the ...
