    Polynomial Remainder Theorem

    Hi, I hope someone can provide me with some clarification. I'm trying to find the remainder for a dividend of x^2+9x-7. I already have information regarding the quotient and divisor: (x + 3) and (x + 5). It's unknown which one is the quotient or divisor, but I don't think that's relevant...

    Specific case of 5th degree polynomial equation

    I know that for the nth degree polynomial equation (where n>4) there is no general solutions. I wonder if it possible to solve special case of 5th degree polynomial equation which lacks linear and quadratic terms. a1x5 + a2x4 + a3x3 = b, where a1,a2,a3, and b are positive real numbers. any...

    Degree of accuracy (Polynomial interpolation)

    Degree of Lagrange polynomial and error Can you help me? Consider the function f(x)=e^{x-1} on the interval 0\leq x\leq1. For all N=1,2,... we have the uniform partition x_i=ih, i=0,1,...,N, h=1/N. If we want to use Lagrange polynomial to make an approximation of f(x), what should be the...

    How to write a spanning set for a polynomial of degree three

    How do I get from p to the spanning set? I understand how to get here. p(x) = (x-2)(x-3)(ax+b) How do I get to the spanning set in the image above? I really need to see it step-by-step.

    Polynomial of the 4th degree.

    I have to determine P(x) polynomial of the 4th degree if i know 4 of his points: (-2, 4a+8), (-1, a-8), (0, -4), (1, a+2), (2, 4a+16) a is real number. For which value of a polynomial has two roots whose product equals 2? I know that this means following: P(-2)=4a+8 P(-1)=a-8 and so...

    Determining Degree of Unknowns in Polynomial

    x^2(y + z) = 3 or x^2y+x^2z=3 : x; x and z; x, y, and z; I got the polynomial as being of degree 2 in x, 3 in x and z, and 4 in x, y, and z. However, the book says x, y, and z are degree 3. My question is how is this so, or is the book wrong? I am adding together the 2 from x^2 and each 1 from...

    I'm confused. Characteristic polynomial of degree less than n... Impossible? well...

    The characteristic polynomial of a matrix M\in \mathbb{F}^{n\times n} must be of degree n, as far as I know. Consider the following matrix M\in (\mathbb{Z}_2)^{2\times 2}: M=\begin{pmatrix}1&1&0\\1&0&0\\0&0&1\end{pmatrix} If we try to calculate its characteristic polynomial, we get...

    does e^nx = (1 + x)^n to first degree of x

    I think I am supposed to use the Maclaurin Series for both sides: {e}^{nx} = 1 + nx{e}^{nx} and {(1+x)}^{n} = 1 + nx So is the answer that in the lim x-> 0 it is true because {e}^{nx} -> 0 Thanks :)
