If a polynomial function f(x) has roots 0, 4, and 3+√11, what must also be a root of f(x)?

A polynomial function P(x) of degree 5 with leading coefficient o

Given all the roots of a polynomial, I have to figure out an algorithm that generates the coefficients faster than O(n^2). I'm having trouble approaching this problem. I'm pretty sure I'm supposed to use the concept of a Fast Fourier Transform or Inverse Fourier Transform, but I don't know how to modify the...The rule, using a polynomial function of the lowest order is Un = (12n3 - 36n2 - 145n + 413)/25. Because the vertex is the lowest point on the graph, and 1>0, there is no way for it to touch the x-axis.NOTE: But if we're considering imaginary numbers, the values "i" and "-i" would be the zeroes.Degree, Leading Coefficient and Constant Term of Polynomial Function. • 57 тыс. просмотров 1 месяц назад. What is the Degree of a Polynomial? |Low degree polynomial equations can be solved explicitly. Polynomials provide good examples for studying more general functions. The term an is assumed to be non-zero and is called the leading term. The degree of the polynomial is the largest exponent of x which appears in the polynomial...We know that the complex roots always occur in conjugate pairs. One complex root is ##1+i##, so there must be its conjugate, i.e., ##1-i## as the other root. Therefore, the poly. of the least degree must be a cubic having ##3" zeroes, "1, 1+i, and, 1-i##.

(*1*)Desired roots:

(*1*)x = 1

(*1*)x = 1 + i

(*1*)But as a result of now we have a posh root, we will have to have its conjugate (1 - i):

(*1*)x = 1 - i

(*1*)Now write each of the ones as equations equal to zero:

(*1*)x - 1 = 0

(*1*)x - (1 + i) = 0

(*1*)x - (1 - i) = 0

(*1*)Rewrite the final two as follows:

(*1*)(x - 1) - i = 0

(*1*)(x - 1) + i = 0

(*1*)Multiply those remaining two together:

(*1*)[ (x - 1) - i ][ (x - 1) + i ] = 0

(*1*)We have the set-up for a difference of squares --> (a - b)(a + b) --> a² - b²

(*1*)(x - 1)² - i² = 0

(*1*)(x - 1)² - (-1) = 0

(*1*)(x - 1)² + 1 = 0

(*1*)(x² - 2x + 1) + 1 = 0

(*1*)x² - 2x + 2 = 0

(*1*)But then we need the last factor of (x - 1) also multiplied in:

(*1*)(x - 1)(x² - 2x + 2) = 0

(*1*)Distribute:

(*1*)x(x² - 2x + 2) - (x² - 2x + 2) = 0

(*1*)x^3 - 2x² + 2x - x² + 2x - 2 = 0

(*1*)Combine like phrases:

(*1*)x^3 - 3x² + 4x - 2 = 0

(*1*)That's the polynomial function with the desired degree and the main coefficient of 1.

(*1*)f(x) = x^3 - 3x² + 4x - 2

(*1*)The following hyperlink confirms the roots:
