WebHow do I find all the rational zeros of function? To find the zeroes of a function, f (x), set f (x) to zero and solve. For polynomials, you will have to factor. For example: Find the zeroes of the function f (x) = x2 +12x + 32 First, because it's a polynomial, factor it f (x) = (x +8)(x + 4) Then, set it equal to zero 0 = (x +8)(x +4) WebUse the Rational Zero Theorem to list all possible rational zeros of the function. Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial. If the remainder …
