The fourth-degree polynomial f (x) = 230x4 + 18x3 + 9x2 − 221x - 9 has two real zeros, one in [−1, 0] and the other in [0, 1]. Attempt to approximate these zeros to within 10−6 using the
a. Method of False Position
b. Secant method
c. Newton's method
Use the endpoints of each interval as the initial approximations in (a) and (b) and the midpoints as the initial approximation in (c).
