1. Use long division to divide. (4x^3 - 2 - 8x + x^4) ? (x^2 - x - 2)
2. Function f(x) = 10x3 - 27x2 - 120x + 25
Factors (2x + 5), (5x - 1)
(a) Verify the given factors of the function f.
(b) Find the remaining factor(s) of f.
(c) Use your results to write the complete factorization of f.
(d) List all real zeros of f.
x =
x =
x =
3. Function g(x) = 6x4 - 17x3 - 91x2 + 272x - 80
(a) Use the zero or root feature of a graphing utility to approximate the zeros of the function accurate to three decimal places.
x = -4
x =
x =
x = 4
(I guessed 4 and -4. they are correct answers, but idk how to get the other two)
(b) Determine one of the exact zeros.
x =
(c) Use synthetic division to verify your result from part (b), and then factor the polynomial completely.
g(x) =
Thank you!!
