Nov 12, 2011 · Form a polynomial, f(x), with real coefficients having the given degree and zeros. Degree: 3; zeros: 1 – i and -6 This polynomial has decimal coefficients, but I'm supposed to be finding a polynomial with integer coefficients. So I'll first multiply through by 2 to get rid of the fractions: 2(x 3 + 2.5x 2 – 14x – 7.5) = 2x 3 + 5x 2 – 28x – 15. Then my general form of the polynomial is a(2x 3 + 5x 2 – 28x – 15). Plugging in the point they gave ... It happens that if you take the set of all polynomials together with addition of polynomials and multiplication of a polynomial with a number, the resulting structure satisfies these conditions. Therefore it is a vector space -- that is all there is to it. Nov 12, 2011 · Form a polynomial, f(x), with real coefficients having the given degree and zeros. Degree: 3; zeros: 1 – i and -6 In each case, the weighted sum of these basis polynomials is the interpolating polynomial that approximates the given function. The Matlab code that implements the Newton polynomial method is listed below. The coefficients can be generated in either the expanded form or the tabular form by recursion.

PART A: TECHNIQUES WE HAVE ALREADY SEEN Refer to: Notes 1.31 to 1.35 Section A.5 in the book Notes 2.45 Refer to 1) Factoring (Notes 1.33) The polynomial is general written on the form a n x n +a n-1 x n-1....a 1 x+a 0 where a is a real or complex number and n is an integer. To enter a polynomial you just type 'naturally' E.g. x^3-3X+4 and hit the Solve Equation button to find all the roots. According to the complex conjugate root theorem if f (x) is a polynomial in one variable with real coefficients, and x + yi is a root of f where x and y are real numbers, then its complex conjugate x − yi is also a root of f (x). The complex conjugate of 2 - 5i is 2 + 5i. The roots of f (x) are: 2 - 5i, 2 + 5i, and 3 with multiplicity 2. 4) If P(x) is a polynomial of odd degree with real coefficients, then the equation P(x) = 0 has at least one real solution. 5) For a polynomial equation with a n as the leading coefficient and a o as the constant then the following is true: a) the sum of the roots is - a n-1 /a n b) the product of the roots is: a o /a n if n is even-a o /a n if ... 111.
