10.3 Descartes' Rule of Signs (a) If c. C2, ..., Cm are any m nonzero real numbers, and if 2 consecutive terms of this sequence have opposite signs, we say that these 2 terms present a variation of sign. With this concept, we may state Descartes' rule of signs, a proof of which may be found in any textbook on the theory of equations, as follows: Let f(x) = 0 be a polynomial equation with real coefficients and arranged in...
Use the rational zeros theorem to find all the real zeros of the polynomial function. Use the zeros to factor f over the real numbers. f(x) = 2x2 - 4x2 - 38x + 76 Find the real zeros off. Select the correct choice below and, if necessary, fill in the answer box to complete your answer. A. x = 2,719,- 19 (Simplify your answer. Type an exact answer, using radicals as needed.Use integers or fractions for any rational numbers in...
