Example for Problems 1-10• P(x) = x 4 -3x 3 + 5: There are either 2 or 0 positive realroots, 0 negative real roots, and 2 or 4 imaginary roots;therefore, you would only synthetically divide the integersfrom 0 to 4.1 1 -3 0 0 51 -2 -2 -21 -2 -2 -2 33 1 -3 0 0 53 0 0 01 0 0 0 52 1 -3 0 0 52 -2 -4 -81 -1 -2 -4 -3Since I have two sign changesI know I have located therelative position of the twopositive roots. Now I have tocheck the half units to see ifthey are closer.
