1 ? < 40. The cubic x³ - 2x² - x + 1 has three real roots; one is negative. a. Find a rearrangement that converges to the negative root. Will this converge to either of the positive roots? b. Find a rearrangement that will converge to the larger positive root. Will this same rearrangement con- verge to the other roots? c. Find a different rearrangement that converges to the smaller positive root. Does it work for the other roots?
