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).
#c=10#. The solution to any of these problems is known as the quadratic equation: #x = (-b +- sqrt(b^2 - 4 a c))/(2a)#. The reason there is a #+# and a #-# in the top just means that there are two possible answers for x, and you need to try both signs to get both answers. The discriminant is just defined as the stuff in the square root of the expression:
