Let us take an example of the polynomial p(x) of degree 1 as given below p(x) = 5x 1 According to the definition of roots of polynomials, 'a' is the root of a polynomial p(x), if P(a) = 0 Thus, in order to determine the roots of polynomial p(x), we have to find the value of x for which p(x) = 0 Now, 5x 1 = 0 x = 1/5Polynomial functions are the most easiest and commonly used mathematical equation It can be expressed in terms of a polynomial The polynomial equation is used to represent the polynomial function Generally, a polynomial is denoted as P(x) The greatest exponent of the variable P(x) is known as the degree of a polynomialIf x= p q is a rational solution to the polynomial equation f(x) = 0 then qx pis a factor of the polynomial f(x) and so we can use long division to write f(x) = (qx p)g(x) where g(x) is a polynomial of smaller degree We teach a version of this method in high school when students learn to solve quadratic equations by factoring

P(x) formula polynomial
P(x) formula polynomial-If P(x) is a polynomial in x and k is any real number, then the value of P(k) at x = k is denoted by P(k) is found by replacing x by k in P(x) Example 2 In the polynomial x 2 – 3x 2, Replacing x by 1 gives, P(1) = 1 – 3 2 = 0 Similarly, replacing x by 2 gives, P(2) = 462 = 0 For a polynomial P(x), real number kF(x) =4x³2x²8x21 and g(x) =7x²3x12 are polynomials in variable x whereas p(y) =2y²3y4 is a polynomial in a variable y 7x³2x²3√x is not considered as a polynomial because the exponent of x in 3√x is not a positive integer

The graph is shown at right using the WINDOW (5, 5) X (8, 8) The maximum point is found at x = 1 and the maximum value of P(x) is 3 The coordinates of this point could also be found using the calculator Polynomials of degree greater than 2 Polynomials of degree greater than 2 can have more than one max or min value(Yes, "5" is a polynomial, one term is allowed, and it can be just a constant!) These are not polynomials 3xy2 is not, because the exponent is "2" (exponents can only be 0,1,2,);If P(x) is a polynomial in x and k is any real number, then the value of P(k) at x = k is denoted by P(k) is found by replacing x by k in P(x) Example 2 In the polynomial x 2 – 3x 2, Replacing x by 1 gives, P(1) = 1 – 3 2 = 0 Similarly, replacing x by 2 gives, P(2) = 462 = 0 For a polynomial P(x), real number k
Example 2x 3 −x 2 −7x2 The polynomial is degree 3, and could be difficult to solve So let us plot it first The curve crosses the xaxis at three points, and one of them might be at 2We can check easily, just put "2" in place of "x"How To Given a graph of a polynomial function, write a formula for the function Identify the xintercepts of the graph to find the factors of the polynomial;The calculator accepts both univariate and multivariate polynomials Show Instructions In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x` In general, you can skip parentheses, but be very careful e^3x is `e^3x`, and e^(3x) is `e^(3x)`

Introduction to Polynomial Equation If p (x) is a polynomial equation in x, then the highest power of x in p (x) is called the degree of the polynomial p (x) So, p (x) = 4x 2 is a polynomial equation in the variable x of degree 1If a polynomial of lowest degree p has zeros at x= x1,x2,,xn x = x 1, x 2, , x n, then the polynomial can be written in the factored form f (x) = a(x−x1)p1(x−x2)p2 ⋯(x−xn)pn f (x) = a (x − x 1) p 1 (x − x 2) p 2 ⋯ (x − x n) p n where the powers pi p i on each factor can be determined by the behavior of the graph at the corresponding intercept, and the stretch factor a can be determined given a value of the function other than the x interceptGiven a set of n 1 data points (x i, y i) where no two x i are the same, one is looking for a polynomial p of degree at most n with the property =, =, , The unisolvence theorem states that such a polynomial p exists and is unique, and can be proved by the Vandermonde matrix, as described below

Constant polynomial is a function of the form p(x)=c for some number c For example, p(x)=5 3 or q(x)=7 The output of a constant polynomial does not depend on the input (notice that there is no x on the right side of the equation p(x)=c) Constant polynomials are also called degree 0 polynomials The graph of a constant polynomial is aUsing your notation, we know that the product p (x) q (x) is a polynomial of degree n mQuestion The polynomial of degree 5, P(x) has leading coefficient 1, has roots of multiplicity 2 at x=1 and x=0, and a root of multiplicity 1 at x=−3 Find a possible formula for P(x) P(x)= Answer by Alan3354() (Show Source)
