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).
The discriminant in a quadratic equation is found by the following formula and the discriminant provides critical information regarding the nature of the roots/solutions of any quadratic equation. discriminant= bÂ² â 4ac. Example of the discriminant. Quadratic equation = y = 3xÂ² + 9x + 5.
