The causes of back pain are nearly as numerous as terms used to describe the symptoms. Back pain is a primary reason people seek medical attention. Considering that almost 80% of the adult population will encounter some form of back pain, it could be said that back pain is a universal epidemic.
Multiplicity of a root of a polynomial[edit] Let F be a field and p(x) be a polynomial in one variable and coefficients in F. An element a â F is called a root of multiplicity k of p(x) if there is a polynomial s(x) such that s(a) â  0 and p(x) = (x â a)s(x).
One obvious root of this is x = 1, so (x-1) is a factor. Use long division of (x3 -1)/(x-1) and the quotient (x2 + x + 1) will be another factor. So (x3 -1) = (x-1)(x2 + x â¦ + 1).Remember that a cubic polynomial will always have 3 roots. It will either be 1 pure real root and 2 complex roots, or 3 pure real root.ne obvious root of this is x = 1, so (x-1) is a factor. Use long division of (x3 -1)/(x-1) and the quotient (x2 + x + 1) will be another factor. So (x3 -1) = (x-1)(x2 + x â¦ + 1).
