Web59. The typical approach of solving a quadratic equation is to solve for the roots. x = − b ± b 2 − 4 a c 2 a. Here, the degree of x is given to be 2. However, I was wondering on how to solve an equation if the degree of x is given to be n. For example, consider this equation: a 0 x n + a 1 x n − 1 + ⋯ + a n = 0. polynomials. WebIn mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer powers of variables. An example of a polynomial of a single indeterminate x is x2 − 4x + 7.

WebWe can turn this into a polynomial function by using function notation: f (x) = 4x3 −9x2 +6x f ( x) = 4 x 3 − 9 x 2 + 6 x. Polynomial functions are written with the leading term first and all other terms in descending order as a matter of convention. In the first example, we will identify some basic characteristics of polynomial functions. WebAnswer: It depends on how the variable is defined. If we are just saying something like \sqrt x, this is not a polynomial. We define polynomials to be the sum of products of integer powers of one or more variables, and can offer up the generic polynomial a_1x^{m_1}y^{n_1}+a_{2}x^{m_2}y^{n_2}+\l... on upward trend
