WebAug 3, 2016 · Precalculus Polynomial Functions of Higher Degree Zeros 1 Answer George C. Aug 3, 2016 f (x) has zeros 1, −2 and ±2i Explanation: f (x) = x4 + x3 +2x2 + 4x −8 First note that the sum of the coefficients of f (x) is zero. That is: 1 + 1 + 2 + 4 − 8 = 0 Hence f (1) = 0, x = 1 is a zero of f (x) and (x − 1) is a factor: WebThis number "four" is the maximum possible number of positive zeroes (that is, all the positive x-intercepts) for the polynomial f (x) = x 5 − x 4 + 3x 3 + 9x 2 − x + 5. Affiliate However, some of the roots may be generated by the Quadratic Formula , and these pairs of roots may be complex and thus not graphable as x -intercepts.

WebJul 16, 2016 · Explanation: Since there are no terms of odd degree, we can treat this as a quadratic in x2 to simplify it, then factorize each of the resulting quadratic factors. First note that 36 = 9 × 4 and 9 + 4 = 13, so we find: x4 −13x2 + 36. = … WebJul 20, 2024 · We want to find the zeros of this polynomial: p (x)=2x3+5x2−2x−5 Plot all the zeros (x-intercepts) of the polynomial in the interactive graph. • ( 1 vote) David Severin 2 years ago The first way to approach this is to see if you can factor out something in … the sweet potato diet pdf
