WebThe Factor Theorem is another theorem that helps us analyze polynomial equations. It tells us how the zeros of a polynomial are related to the factors. Recall that the Division Algorithm. If k is a zero, then the remainder r is f(k) = 0 and f(x) = (x − k)q(x) + 0 or f(x) = (x … WebAug 19, 2024 · I am to find all the zeros of $2x^3+5x^2-12x-30$ given one factor $2x+5$. ...

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: WebApr 24, 2024 · The zeros of a polynomial function of x are the values of x that make the function zero. For example, the polynomial x^3 - 4x^2 + 5x - 2 has zeros x = 1 and x = 2. … datatable format money
