WebA value c c is said to be a root of a polynomial p(x) p ( x) if p(c) = 0 p ( c) = 0. The largest exponent of x x appearing in p(x) p ( x) is called the degree of p p. If p(x) p ( x) has degree n n, then it is well known that there are n n roots, once one takes into account multiplicity. WebThe ABC Formula. Another way to find the roots of a quadratic function. This is an easy method that anyone can use. It is just a formula you can fill in that gives you roots. The formula is as follows for a quadratic function ax^2 + bx + c: (-b + sqrt (b^2 -4ac))/2a and (-b - sqrt (b^2 -4ac))/2a. These formulas give both roots.
