Find polynomial function with given zero
WebExplanation: If the zeros of a polynomial function are given, then we can write the function as a product of factors, one for each zero. Specifically, if r is a zero of a polynomial function f (x), then (x - r) is a factor of f (x). In this case, the given zeros are -3, 0, 2, and 1, so we can write the polynomial function in factored form as: WebGiven that the polynomial function has the given zero, find the other zeros. f (x) = x 3 + 8 x 2 − 5 x − 40; − 8 The other zero(s) is/are 5 , − 5 . (Type exact answers, using radicals as needed. Use a comma to separate answers as needed.)

WebFeb 24, 2024 · About this tutor ›. So it looks like the given zeros are 2i and -3. We have to work backwards. x = -3 and x = 2i. For -3, we know that out factored form before would have been x + 3. For 2i, that means we took the square root of negative number because it is imaginary. So that means out factored for x 2 + 4. So if we put these together: WebJan 16, 2024 · Simplifying gives: f (x) = x(x + 2)(x +3) From here, we can put it in standard polynomial form by foiling the right side: f (x) = x(x2 +5x +6) And distributing the x yields a final answer of: f (x) = x3 + 5x2 +6x. To double check the answer, just plug in the given zeroes, and ensure the value of the function at those points is equal to 0.
WebFind a polynomial function of the lowest order possible such that two of the roots of the function are: Recall that by roots of a polynomial we are referring to values of such that . Because one of the roots given is a complex number, we know there must be a second root that is the complex conjugate of the given root. This is .
